I have a giant trampoline....fun stuff.
I was never really a wizard with tricks, but I can jump wicked high, even by giant trampoline standards. I managed a double flip once, but wouldn't be able to it anymore (out of practice).
My favorite is flipping half-way, then "diving" toward the trampoline head first....then rolling into the tramp at the last second....scares the sh*t outa anyone seeing it for the first time, because it looks like I'll break my neck. I call it teh stage dive. 😎
