To be honest the blueprint is fairly straightforward ... hard work.
The two projects in the Showgrounds at the moment are the clubhouse and new seating in the stands. These have been done by non-committee members that volunteer.
Edit: And the Annual draw is on at the minute too. Every house in the town and county (and beyond) will be knocked on by volunteers selling tickets. It usually takes in north of 60k per season.
