Oh, rest assured that there are hidden areas of this forum that most people don't know about... Steve and I have been all over this topic in recent months! But, if we post our discussion here, then we spend 10x as much of our time fielding questions from all of the well-meaning folks trying to help.
We are currently in the process of doing a serious "feasibility study" to determine if we CAN build a facility. Initial indications are that we probably can, with enough crowdfunding support, and help from "all the right people". But, until we have CONFIDENTLY answered that question, there is no point in going further. So, that's where we are. We're passing our initial investigation off to people who are professional construction project managers for their input.
FAST is not a non-profit, btw. Never has been. It's a MAJOR hassle to get set up as a non-profit. In the beginning, we just didn't think it was worth the hassle. But, since then, the club has grown a lot, and we put in a LOT of work... and we accept some of the profit. (yeah, we could still take a salary even if it was non-profit) But, we'll look at all of the real estate options when the time comes. We're just not there yet.
Event insurance is handled at the club level. As site owners, we may have our own liability insurance on top of that. But, every autocross club carries insurance and insures their own events. WE don't want to be responsible for somebody else's event. They make mistakes and OUR premiums go up? No thanks.
