i know this is off topic, but have you ever talked to the weavers (xrra)or rich cline (werock)about having a real event there? even spring hill, as small as it is, has a nice course and they were really raking in the people at their events couple years ago....
youve got the parking space, decent location, maybe time to put a real rock course in???
could plan a late season big event/ numerous small comps per year ...hint hint..
