I was also giving rock crawling lessons to OldYellerCJ and LittleSkittles, both did really good, and both got stuck, LittleSkittles on a dead/fallen log which OldYellerCJ and I put back where it was, and OldYellerCJ on the same small rock pile I got stuck on, but much worse, we had to high-lift the front axle up so we could back it off the pile.
I'll have more pics up of the big rock pile after I get the film (i know, what's that?) developed.
