To add to your list of things to do when you’re out of things to do on the Internet (yes, it can happen): search yelp.com for reviews of U.S. post offices. I found a review of the tiny neighborhood post office I like to use, a murder location in Chicago, a happy encounter with a nice guy in NYC, and raves upon raves for a San Francisco USPS open until midnight. Who knows what else lurks in the other corners of the country?
