Was that Gold Mountain or John Bull at that point?
FWIW I watched Jeeper John high center himself on a 4' tall round rock with multiple tires in the air on a couple tries. When success came with using momentum to get past the same high centering it was a pretty violent manuever that got the job done.
I was enjoying the spectacle too much to run back for my camera parked at the back of the pack. However, that rock was scratched to hell by the time John's undercarriage was done with it.
