I try to do this, but don’t always.
Also, insert lament here for the fact that many Catholic church buildings these days don’t look distinctively Catholic from the outside. There are a few of those around here, including my own parish, St. Mary’s (and actually we’re in the midst of a massive renovation project). Although one of them, St. Francis de Sales parish, has a cool “city on a hill” motif going on – it’s perched on top of a giant hill overlooking I-68, at Exit 1 (US 119). It’s especially visible if you’re headed westbound on 68, toward its end at I-79 – look to your left as you approach the exit.
