Precisely!
I've been involved in this hobby for decades as well, and seen this sort of argument go 'round and 'round over and over again. I get it, but you're overlooking the obvious here chaps.
And it's been my experience that the only way to guarantee yourself racers' participation in setting up and taking down is by
not charging entry fees for the races. That way, only the ones doing the actual work are allowed to run their cars.
Otherwise, once you hold out your hand demanding entry fees - then you lose the right to demand people to do more than just race and leave, as it's their right to do so.
They paid for the right to race, they didn't pay for the right to pick up the track.
At the same time, once you open it up to excuses why "some" shouldn't have to help - regardless what that excuse might be - you open yourselves to ANY other excuse.
Sorry for being brutal here -- but if one has physical limitations you're "supposed" to get a substitute marshal to take care of your duties, so by the same token you should rightly bring someone to take up your share of the track at the end of the night, and if your excuse is that you brought your small children and they need to get off to bed, then you shouldn't bring your children out at night.
Reading around this forum, every time I turn around it seems there's some club that's shutting down their program, or threatening to, due to lack of sufficient numbers (and their entry fees) to support renting a hall or venue to hold races.
Why do you think this is happening?
I'll tell you. While there are a lot of potential explanations, at the end of the day (for one reason or another) racers end up not feeling welcome and don't end up returning. They either quit altogether, or they find somewhere else they feel more welcome.
I understand, I totally "get it." I've been involved in running clubs, running races, designing tracks, putting them up and taking them down - the issues haven't changed from 30 years ago to today, and they're not going to change in the future. You've got to come to grips with the fact that some people are workers, some enjoy participating, some don't, some are lazy, and others just need to leave early. Dealing with it is part of running a club and having races. If you can't deal with it, then stop running races and allow those with more patience to do it.
It's also been my experience that a surefire way to make racers feel unwelcome is to chastise them publicly and become aggressive with your approach to them. Grow men don't appreciate being dealt with like they're children, even by their mums, regardless if you think they're right or wrong.
