You guys do realize most of these parks don't let you in for a very good reason that someone already mentioned. It's not they are hating on the sport. They simply do not have insurance for it. So if one of you were to get hurt in the park, you could sue the park and win because they are not insured or have anything in their contract about scooters. The people that do let you in most likely don't care, or they have a more general contract that states that just using the facility at all, with anything, is under insurance and people do so at their own risk.
