We mostly plan to keep it rec play, we are trying to keep it as friendly as possible. We had groups of kids also, they had the time of their life. You told me earlier that it's a good idea to turn the velocity down for the youngins, I heeded that advice and did so.
We got a portable chrony so we can closely monitor the markers if needed (a German Virtue Clock II).
Best turnout was about 40-50 people a day and we didn't get into serious advertising yet.
We live in the NW corner of Hungary, where we have a tri-border area, we aim to do get people from Austria and Slovakia too, so hopefully we will be booked full next year.
HPA would be nice, but at the moment it is out of the question, maybe in a year or two once we got the investment back and start turning a profit.
Property damage (unless intentional of course) is covered by the owner's insurance, so we only have to worry about injury related stuff, but we have a blanket sports group-insurance for that.
Once more, thank you very much for your patience and feedback.
