Sure thing, thanks for setting up this project!

Wow, is that "big Central PA blob" one single multipolygon? I can see how that might cause issues.

Sounds good. I pulled the name off the Allegheny County Parcel Viewer, but I see on street view that the sign doesn't include "garden." I updated the name

Agreed, I think I only added one trail I walked along a gas line that was well established. I believe I adjusted a few others based on GPS and topo, but many were quite rough. I plan to return after fall when they are less dense with vegetation to figure out which are passable and which are not.
