JV is located in the monsoon track that comes up from the Gulf of Mexico, similar to Tucson. Rain there is our friend - it really cleans up the tails and both moves and re-exposes the rocks. The best time I had out there was in October 2 years ago - some of the trails had no tire tracks when we got to them which really made them a pleasure to drive. Nothing worse than trying to negotiate a chuckhole at the bottom of an obstacle left by some idiot with 38" Swampers, a gas pedal and no sense
