Sorry if I wasn't clear; I wasn't thinking of using the geometry on 
those monochrome maps directly, just referencing them for things like 
trail names, trail colors, and other stuff like where gates and 
bathrooms might be near.

I did get the DCR MassGIS data working within iD (just took waiting for 
a while for it to load) and added the links to the MassGIS wiki page. I 
agree that the geometry wasn't any better than any other GPS trace, but 
it was good enough to know where to look at the aerial imagery and LiDAR 
relief data, and it does have trail names in it and such.

Thanks all.
