Hello Lisa,
We use Gales creek special events insurance.
http://www.galescreek.com/
I had done hours I mean days of searching the insurance companies and they beat all quotes from Sportsman, and others. They also were real easy and friendly to deal with. When I added the extra pool during the Katrina jump the city needed me to up the insurance and add seperate liability. Gales worked with the city themselfs and I never was bothered with any of it. (Including extra costs)
