There is an area in the desert about 2 miles northwest of my house that has been open to the public, including using motorized vehicles. There have been numerous caches placed in the area. Sometime in the last week or so the City of Scottsdale posted signs indicating that motorized vehicles are now prohibited, and anything prohibited carries a penalty. Another indicator of encroaching tyranny – small steps, like throwing a frog in cold water and slowly increasing the heat.
