(Plus, it's been 11 years and the trails might have changed--it wouldn't hurt to survey them again.)

It means they need further surveying--I surveyed parts of some trails, but others were based on Bing and/or a rough estimate based on my survey.

Okay, those fixmes I added were just confusing, so I've removed them.

(I was trying to indicate that those buildings have addresses from 500 to 510, but I don't know which address goes with which building.)

Unfortunately I don't remember why I removed the tags. Maybe I was trying to replace that way with a multipolygon, but I forgot to add the multipolygon.
