Wow! That's amazing. The guy launches this thing from the Downtown Disney auxiliary parking lot behind the Paradise Pier Hotel. Gutsy!
But then, according to the date on the video this was taken during Easter Vacation and they had parked that auxiliary lot for theme park guests. So it was busy and he wouldn't have attracted any attention from the parking staff because that lot was already full of cars and people. I'm sure this is all sorts of illegal, but it's a fun video to watch!
