I went airborne like that once by accident and almost sh*t my britches. Going about 60mph on a hill very similar to that (back to back hills actually) and made the mistake of twisting throttle as I was going over the top. Good thing I was hanging on to the bars b/c my butt was way off the seat, like a dirt rider, both wheels off the ground and came right back down no problem. It's actually pretty easy to do in a straight line. That hill has a slight turn to it. Looks like fun.
That road in my Avatar is it - Scott Rd., Folsom, CA
