"Choo Choo Far Away Church!"

This is what Mac says every time he hears a train whistle in the distance. Presumably, this is because the most frequent time we see trains is on our way to downtown, and our most frequent reason for going downtown is to go to church.

Like most kids his age, he can HEAR the train, and he NOTICES it. I never realized how often I tuned stuff like that out until he began pointing it out to me.
