More Fun than a Costco Box?

I think Colin's end was a train (of course) and Gillian's end was not a train, but I can't quite remember what it was! We had a fun run to Costco last week. The kids love to go there. They like the big, double carts and the fun stuff to look at. And the free samples. Oh, yeah, and there are two tracks that have very heavy freight train traffic RIGHT outside the front door of the store! We saw three, YES THREE, trains last week!
