Sounds fine. I will be at the Kid's Fun Fly in St.Charles on June 7th during the earlier hours -- kids fly the club trainer airplanes for free and (I think) 2 kids will win a complete airplane set. See foxvalleyaero.com. Maybe later on in the day or sometime early on Sunday.
In fact, I hope to buy some of the railroad ties and start building it this weekend.
I thought a stand is really one of the basics that a track must have. The scoring system is not in place. I imagine I would go with a human pressing some keys on a computer as the cars pass by (like the McHenry HobbyTown long ago), depending on how much interest develops.
