What Desert areas are still legal to ride??

Are you still riding. There are few to none down here in Tucson, Panal air park is pretty cool. Otherwise there are plenty of tracks near PHX, AZ

Best desert trails in my opinion (that are still open) are 1) Wildcat staging area up near Bartlett lake on the dam road 2) Rolls OHV near 4 peaks 3) Sycamore creek area. The area near Piralta trail off of the 60 (opposite side of the road) just past the Renaissance Fair has a couple decent spots, but in general it's not nearly as good as the 3 above.
