GBIFID: 3039483878; Occurrence Remarks: I used to camp in this area because there wasnÆt anyone really back here (ItÆs a nice place to camp and hike up to the ridge line and back down around). It is insane how much traffic there is now. I pulled a few cars out that got stuck trying to cross washes or drive fast and broke car parts. I donÆt typically go here anymore because of how many people are back there now. It was a nice few cruises from Tucson to Tombstone. Kinda hard to pass without at least looking, even if it feels like some kinda competition to see things on these popular trails or roads.;; Coordinate Uncertainty in Meters: 29146.00000.
