Trampoline Guards

I really want a springboard for me and my friends a bit cold on it but the only way I can get is if I am a guardian of the child. What are the things I can do to guard not so lame?

Grow plants up there! Vines, beans, clematis ... vines.

Well ... I do not have a trampoline, but have been on them. It might be difficult at first, if this is your first time, but on a trampoline some cool stuff, is something like flips. The only thing that keeps me from saying go ahead and do flips, is able to land on your head causing potential harm. But be careful and be safe and have fun is more important. So just try what you want to try to find stuff that you go. Hope I helped:)
