How about
1 Club night tuesdays 10th off road buggies
2 Trucks, ST & vintage Thursdays
3 Buggies & micro's Fridays, (Midlands raceway do this and it gets fairly busy in both classes)
Just a suggestion.
3 nights a week i'm sure that this will easily cover financial viability issues as well as keep most people happy.
Im sure if the jumps were removable you could even run touring cars on a wednesday which also has a large following.
$$$ KEERRCCHING!!! $$$
I hope you all agree
If not I will happily accept any abuse
See you all at WS
