This is the time of year when I re-familiarize myself with the lobbies of buildings that I neither work nor live in.
I'll explain. A lot of downtown Chicago buildings take up the whole city block and have entrances at both ends. So on the bitterly cold or very snowy days, I walk through as many of these buildings as I can to avoid whatever conditions Winter is throwing at us that particular day. Depending upon where you are and where you need to go, you can do pretty well without going too far out of your way.
And sometimes, like with this display of hanging lights in the Prudential Building, you can still enjoy the "snow".
