Well, a quid deposit in the 80's didn't stop the early leavers, 2 quid in the 90's didn't work either, so it's got to be 4 to 6 gbp deposit at least now. So I'd vote for a fiver deposit, and free racing for the poor sod who has to take all the money in and then hand it out last thing after the track is all away.
Exceptions of course for those with school kids.
Following on from the MrEmily post, can I suggest the Race Dates thread on here has the committee persons name against the date, showing who will be running it, so gear, keys etc can always be passed on to the one concerned.
PS - thanks for the laugh guys - some of the humour on here is class
PPS - it is a good humoured club - don't think you will find even one club in the country where members are not troubled by those that race and nothing else. Thankfully at Seaham the shirkers are few.
