Casey:
my two boys would be participating. I had planned on taking a few days off with them anyway to get them some extra track time on my own, so I can be available to help out. I would ask that we pick a week as soon as possible as I have child care and holidays lined up and if I need to change them - sooner the better.
Participation has to be with the understanding that it is informal because there are many things to do. If I am there with my boys, then I am basically parenting them - which relieves the club of any liability (in terms of child care issues) - in my opinion. If someone is leaving their kids at the track, then it would be like leaving them with a friend.
I know my sister works with kids (social work degree) and might be able to either help in some way - if anyone thinks there is value in it.
