I learned today that you're well advised to leave lots of (walking to the terminal) time when making early-morning car rental returns to Reagan National Airport, in Washington, D.C.

There's purported to be a shuttle to the terminals. I eventually left a growing group of would-be commuters and set off on foot to find Terminal A for the connection to Minneapolis, MN.

It wasn't too far, which was nice given the temperature -- about freezing.

Here's a picture I took as we were lining up to take off.
