The mini Rubicon doesn't look that bad, but it is. This year it was worse than ever, with holes as big as the FJ itself strung throughout the course. We drew first on the course and should have used our winch to drag big rocks into the holes, but by the time we figured out this plan we were already nose-deep in a Turtle-munching pit. A rig with 90 degrees of approach and departure angle and tight turning shouldn't have any problem with this pile. Yes, the 54-inch tires help fill the big holes, but we've seen small rockbuggy type rigs devour trails like this all over the nation, so we think 39/40-inch tires would be fine here.
