While on vacation in Arizona last week I added areas near Fort Verde, Montezuma Castle and Well and Tuzigoot Monument.
I also added areas around the Apache Trail for Goldfield Ghost Town, Superstition Mountain Museum, Mining Camp Restaurant and some points along the Apache Trail.
I added surface=unpaved to the 20-mile portion of the Apache Trail where it is not paved. I didn't know if I could make it with a small rental car. But it was in good condition, and I had no problems. I guess that is what rental cars are for. I didn't know how far it went so I called the resort at Roosevelt Lake to find out if there was gas nearby.
It's interesting to see the desert areas marked as forests. Technically they are a national forest, but many parts are actually desert scrub. Maybe a landcover import will help there. I also noticed that several of the bodies of water along the Apache trail were missing like Roosevelt Lake and Canyon Lake. Tiger 2009 actually has a good water layer with this data in it. Is anyone interest in uploading it. Or I could do it. Not sure if these would compete with the natural hydrology import I think is being done.
