What kind of "rebound center" are you talking about? I see various uses of that phrase online. Some are places with trampolines, basketball courts and a bicycle shop.
It would make sense to have such centers under a roof and with climate control, in which case the accumulation of ice outdoors would not make much difference.
What is the probable relationship between rebound centers and locations where ice accumulates?
What is the probable relationship between rebound centers and thickness of ice in Canada?
