I noticed some highways have disappeared from near Crater Lake, Oregon. A quick look at the history of the remaining dots (I can get it easily with 'h' in Potlatch 1, no idea if it's possible elsewhere) shows the licensing redaction bot removed them.
Anyway, I added them back (aside: anyone notice how JOSM eventually quits drawing lines between points? the current version is the worst yet) but it really made me sad, since it took a lot of time and really didn't add anything. It would have been nice to just revert back to the original TIGER import.
Maybe the only good that came of this was adding a few more details (bridges) as I went.
