"On a side note, this past year we bought a 15 foot Trampoline for my grandson. Anybody know how that is supposed to be stored for the winter?" How would it work to get a 4 x 8 sheet of plywood and put it over it? would it go edge to edge? It wouldn't have to be cut round, just fit it on top of the floor to keep weather off the tram. Then maybe put a tarp over that, tie it pretty taunt. It's just a thought.
