As far a details on the AZ Land Trust dept, every time I've called them they have been super friendly and helpful...almost eager to talk to people. Then yesterday I got stuck in the I10 parking lot during rush hour traffic. I knew they closed at 4:30pm, and at 4:25 my nav said I had 15 more minutes. I called them and was like "do you really close right at 4:30?" The girl said, "Um, usually...why?" I explained that I'd been sitting in traffic for 45 minutes trying to get there and was 10 minutes away. She put me on hold for a sec, came back and said, "We'll wait for you. Hurry and get here soon". I got there, parked in reserved parking, ran in and they were sitting there waiting for me with smiles. Got me the permit, cashier checked me out and they literally locked the doors behind me. Really a great group of people down there.
Hope this trail is worth it!
