Well well,
I was eager to get my jato in the back woods.. I groomed most of the ramp but I didn't groom the dirt floor, roots were sticking out everywhere! It was still fun though!
This thing jumps like nothing else, it might seem like its hard to control on the dirt but thats just all the guzzillion roots it hitting.
Enjoy
