Idk how any of us survived the 90s with trampolines in constant use! We would jump off them into pools, jump onto them from the roof, double bounce each other half a dozen feet in the air. I even mastered the “art” of jumping off of it and landing on the ground (from 6 feet up), rolling and popping back up.
We also sat in the luggage area of a station wagon with 5 kids on the way to the swimming pool... That would probably get the driver arrested if you did it today.
