Jump And Bye-Bye

I never knew that trampolines were even safe to be used on the rooftops and not only in the open ground areas. Just jump once on a trampoline at that height and you never know from where you might get to jump the next. How can someone even think of placing a trampoline at this height? Lord, save the human who showcases the guts to jump over this one. Even a stuntman would fear once before trying this out.
