Perhaps K&K Insurance out of Fort Wayne, Indiana could help you. They insure a lot of various sports/recreation risks. I don't have a phone number or web address for them...sorry!

Thanks so much to everyone who replied via email to our little plea here. We received many responses and will check them all out.

Does anyone know of a company that will insure skateboard parks? We've come up with zilch so far, and the policy is needed ASAP. Thanks to anyone who has a reply!
