Funny you should mention go carts in this thread...
When I was a 12-13 year old kid I had a friend, Eric, with a go cart who lived about 5-6 blocks south of the DMV test facility in Plymouth, MN (satellite image below), and on more than one occasion we snuck our go carts into the facility late at night via a loose fence we knew about near the back of the property. We never got caught, and imagine the fun we had tearing around the "streets" in near total darkness with our carts...
When it came time to take our driver's tests both of us knew the layout of the place pretty well, and both Eric and I passed on our first attempt. Go figure!
