Unilocal recategorized my previous review as showing this post office in Hoquiam which is about 30 miles from Humptulips, so I don’t know how that happened. Originally written 11/18/2012. This is one of the smallest cutest post offices ever. And with a town name like Humptulips, even cuter. It’s right next to the gas station/convenience store and if you blink, you’ll probably miss it. Anyway, just another stop on my quest to stop in every city in Washington state.
