Wow Fubar, an actual H2 question!?!
This was in the Azusa Canyon off-road park itself (the one that ends in a giant mud bowl), except that the recent rain + reopening of the areas that were closed forever, made the park feel completely new! It was awesome!
We did not wheel with the H3 yet, I followed 3 x H1s. You should see them literally "bounce" on the perimeter of the mud bowl area (which has a solid surface but liquid bottom).. it was crazy to watch -- as if they're driving over a trampoline!
