I've got a 14' trampoline. I want it to be movable. For those unfamiliar, these things can't be dragged across the ground. The tension in the springs (holds the mat to the frame) is what keeps it together. The frame pieces fit together, but the mat + springs is what makes it a single unit. I would appreciate any thoughts/ideas. *EDIT: The need for it to be movable is for mowing etc.
