Jump on Us! is a ridiculously simple idea about which kids and (some adults) are just jumping for joy. This is a play space that consists entirely of trampolines laid into the floor, over a deep pit filled with marshmallow foam mats. There is a roof above, and airy wooden fence around the outside. You pay for 10 minutes and you get assigned a trampoline. Take off your shoes and go crazy! You are only allowed one person on the tramp at a time, so if your kids are little, they can share the 10 minutes. Otherwise, you'll need a tramp for each kid. It's not too much money, and it's well worth it, since this type of thing isn't available around home.
