> guard rail on 118 modified for Greenway a couple weeks ago

Nice! I've never been there, but I can see it on streetside in iD. I've haven't done the 55 or the 40 so my only time doing the middle-bits was on my own. I'll definitely check out the northern-pass next time I swing through there.

I'm on OSM's slack and reddit if you want to talk further, I love your email address.

I wouldn't mind adding "stickers" if they've been printed and approved by the county, or whatever. The old stickers currently there are very confusing. I imagine. On the epic ride, nobody cares, I'm sure, but on a random day, I'm sure everybody can see the "no biking" signs. I made a note of where they all are.

Hi, thanks! I appreciate your link. I'll undo my changes. I saw you undid some of them but not others.

Which 16 miles? This also applies to everything that was in the Moco Epic?

In addition to these sections, I also found a no-biking sign at Frederick Ave (where you climb over the barrier) and Clopper Lake (where you cross the road).

Thanks in advance!

Hey I marked the trail on the East side of Seneca creek as no biking, because there are no biking signs here (as of 2026).

You can only bike on the West side of Seneca creek here.

The cycling heatmap shows this as used because there's an annual biking event here (they open trails to bikes for the event)

Nice ok thanks! I appreciate those details. I made the discussed changes here: changeset/190068616

If you live in the DC area, you should check out Seven Springs. It has some of the best skiing in Virginia, Pennsylvania, and Maryland. They also used to have a bike-park in summer, but I think it's lost to time.

I love this change thank you. I'm a big fan of Seven Springs but I don't live nearby.

Can you explain "Lost Boy" to me?

I think the northern section of Lost boy and The Alley are in the wrong place? I can't confirm this easily, but let me know what you think. I've looked at my GPS traces and the Strava Winter Sports Heatmap and I think they both swing ~500 meters out to the North-East? If you agree, I'll try to move them, thanks!

Oh, very good question. I think we're just proposing things now, but I've been measuring with a tape measure from the lip straight down to the ground. In other words, if you went off too slowly, how far would you fall? So in this case, not far. But yeah, I've never tried to measure a rounded-lip like that: it does seem there are multiple heights. I guess maybe I'd use whatever height was in the middle, or the average of the heights, or something similar.

Yeah, definitely interesting question though, I'm not quite sure of anything yet.

Hello again,

I just noticed this, nice! user pkoby and I have been chatting about the proposal on osmus.slack.com if you want to join, we can make a channel or something. Also discussion can be found here of course: osm.wiki/Proposal_talk:MTB_Trail_Features

Do you know how high this drop is? I've ridden this trail, but I did the Beginner trail and didn't have time for a second loop.

Hello RunTrails,

I noticed bicycle=designated and foot=designated were removed here. I'm not sure I understand, thanks,

Hello Nater Kane,

What is a "spam tag"? Thank you in advance!

Hello htf,

So, I stopped by cabin john today and was thinking of you! I noticed that there ARE biking signs inside the northernmost section of Cabin John Regional Park (so I was mostly wrong). Based on this, I have changed the access to "designated" for biking and foot, for most of the ways in this section.

thanks,

arichnad

Understood, and I agree with everything you said. I probably just missed it. Thanks!

Hello Belle Haven Mapper,

Is the Tot Lot gone these days? I tried to find this back here, and couldn't see it, but I don't go here very often.

I see it in the USGS 3D Elevation Program and I see it in the strava heatmap, but I do not see it on the ground, but maybe I went past it without noticing it. Or maybe it's gone now?

Thanks in advance!

Hello heretofore,

https://montgomeryparks.org/wp-content/uploads/2023/04/Cabin-John-Regional-map-2023-0502-letter.pdf

This map states that biking and foot are designated.

Also, lol, I didn't delete those pictures. Here's a picture of this park:

https://imgur.com/2p5Ryb6

I have a bunch of these (2024), and none of them have the "access types" (the access types signs you mention are further south) but the map link above is sufficient (IMO).

> Didn't one of those trails have a MTB jump line mapped previously?

Ooooh, I didn't see that. I took this picture in 2020 and my memory is that there are a few "bridge like" mtb things:

If there's a jump line, please, let me know!

Thanks,

Hello heretofore,

Yes, I agree. highway=path says "used by pedestrians, small vehicles like bicycles, for animal riding or livestock walking". On the other hand, the wiki does also say "All paths should ideally have access tags"

Also, I can't find it now, but somewhere it says something about adding access if you know it, regardless of the default, and not to remove it. Or something along those lines?

> I think I used to have `designated` values here that someone removed

Wow! Yeah. That's too bad. I must have missed that. I took some pictures of the signposts, but I think I deleted them: my memory is that this park does not have the "mode" (biking/foot/horse) information on them. Maybe? I forget. The ones on the other side of Democracy Boulevard do, I remember that.

Thanks for the discussion!

Hello Heretofore,

I noticed you removed "bicycle=yes" and "foot=yes" in this changeset. I'm not sure I understand this change, I think you're allowed to walk here and bike here.

Thanks in advance!

You're right, my mistake. I understand openhistoricalmap, but I had often seen people leaving parts of the Capital Crescent Trail here as an example (one of many):

way/1308494381/history

I've since familiarized myself with the wiki and I see your position. "There is much debate over what exactly counts as recognizable" Certainly, the remaining parts of this railway are still visible, and verifiable. But also, very hard to see.

Regardless, I've manually undone this edit, thanks!

> basing edits on headmap data in this way ends up not being helpful ... I’m begging you to stop making edits just based on heatmap data.

I'm going to be just only slightly defensive here: I don't. I don't edit just based on heatmap data. I did it here, you're right, but, like I've made a lot of edits the past 10 years and something like ~99% of those edits were based on multiple sources of data: usually one of the sources is being physically on the dirt where the trail exists. I record hundreds of GPS recordings per year where I walk and ride. I even rode very near this trail in August when I made these edits, as you and I discussed in 2025, but sadly, as you noticed, didn't make it over to this particular trail.

Now that I'm done being defensive, this is definitely a screw up on my part. So I've effectively undone my changes for the most part: setting this trail as under construction based on your words above.

If you're reaching out to MORE, let me know here, and if not I'll send a message to the MORE trail liaison.

Thanks,

arichnad

Hello again, Nater,

No prob. I'll be totally honest, I haven't been here. In August (2025) I was hanging out a bit south of here as we discussed earlier. I based the "main section of this trail is open" comment on the heatmap information I was able to find. (I don't think I'm able to attach screenshots here, so to see the heatmap data, you have to have a strava account.) Definitely hundreds or thousands of people on foot and on bike are going through this section. I haven't seen the signage at either end of this trail though, sadly, which is why I left the other access tags unset.

Thanks!

Wow, sorry I never replied to this! I have discussed this with who I assume made the complaint, if the complaint was in 2021. I think we came to a common understanding for these paths in 2021, but also they did stop replying to my questions so I'm not 100% sure. Thank you for the note.

Hello Nater,

It's a small section of trail (700 feet long) and hardly worth mentioning.

I marked it as abandoned:highway=path here:

way/1426456597/history

If you didn't notice the trail change, it could be because you didn't swing back close to Benway Court / Bryan Mills Way.

It was "discovered" by me: someone who works for the park or MORE painted over the red blazes with black blazes, and I assume it's not a black trail :) If you look at the strava heatmap, nobody on "cycle" is taking it anymore as it is marked as no longer red.

I discovered it on 2025-08-31 and I assume it's why the cut-through trail was opened in the first place, the cut-through was blazed with red, and it seemed like a new trail to me.

If you've been back there near Bently Court and Bryan Mills Way and you think the trail is open, I'd be 100% fine if you marked it as open, but you should remove the "name=Red Trail" tag.

thanks,

arichnad
