Caution about desert hazards...   Most of the really bad stuff is left by campers...   Burning a pallet for a campfire puts about 80 screw nails into the ashes...   If the fire pit is on the ground and not in an established pit those screws are going to be in the path of off-road'ers within weeks.

Look for a good tire puncture proof product and put in in your tubes before you are 15 miles out in the sun with a flat.   And when you see peeps not watching their trash and fires give them a smack.
