I probably would go without the insurance, but the lovely state of Mn (in collusion with the insurance companies maybe) requires me to have insurance. JImChuk
PS what really gets me is I'm partners in a Chief, I mostly fly my Avid since I rebuilt it last year, and also have the Kitfox 1 which barely got flown last year. The insurance for the Kitfox last year cost me more then the annual and fuel that went through it. No discounts for second or third aircraft like there would be with cars.
