watch out for parent traps

We were doing so well at the fair; I'd gotten my new gardening calendar and Chris had turned in a decent showing at the Krystal contest. Then we walked into trouble.
The model train enthusiasts had a huge display. Along with the Cherry Blossom train, there was Thomas, Annie and Clarabelle. They made one pass, then got taken off the rails for work (or play - I'm not sure). So we stood at the exhibit for another 30 minutes, hoping Daniel would get his fill of the trains. No dice. When we finally dragged him away, he cried. But we were in good company; there were a number of parents and grandparents having the same problem.
So, while there's mich to see and do at the fair, watch out for the parent traps.
