A resent post on MTBR got me Inspired to ride the Arizona Trial up by the Snow Bowl.
( http://forums.mtbr.com/showthread.php?p=5963919#post5963919 ) that post had lots of photos of green ferns and the white bark of the aspens in contrast....Wow! this trail looked sweet.
Just so happened the Prescott Cycling club was planning a camping trip to the lava tube up near the Snow Bowl so off we went four days and three nights of camping and riding.
