Gavin has always liked toy trains. Gabe likes them a little, but Gavin has the patience to sit and watch them go, where Gabe likes to push them around himself. Well, after going to the Polar Express, the boys wanted to play with their Brio trains. Sure enough, as soon as the track was built, Gabe lost interest. But Gavin sat down for a spell, wearing his fashionable new Engineer's cap.
