Backflips!

I think the Backflip is a benchmark trick. For example no one's going to call you an amateur if you can do a backflip on a skateboard. Or BMX. You're immune from mediocrity if you're a Break Dancer who can throw in a good one. At least in the general public eye.

Not too many years ago they did the first Backflip on a Motorcycle, BMX & Snowboard guys were trying the Double Back and Aggressive In Line dudes were going for the Triple.

Now most of that's been done plus they've been able to backflip on a Snowmobile, Kitesurf, probably Jet Ski and really almost anything with an engine.

Really though this has to be the biggest baddest one of them all. Doesn't look all that great but still. It's a MONSTER TRUCK!
