Tips for people coming to DC for the inaugural festivities abound on the interwebs. The one tip that I believe cannot be repeated often enough: When entering or exiting a Metro station via escalator, WALK ON THE LEFT, STAND ON THE RIGHT. [The screaming caps are intentional, thx.] You’ll be among many other tourists, but you will also be among DC residents who aren’t on vacation, who need to catch the next train in order to get to work/school/home/wherever on schedule. Tourists who do not have a tight schedule and who stand on the fucking left despite the polite requests to move (which escalate into frustrated yelling and verbal abuse) from the people bottled up behind them are the biggest pet peeve of most DC regulars.
Also, right now the DC area is suffering the coldest weather on record in the last decade, with wind chilll of -1F or more. It’s freezing out, so remember to bring hats, gloves and scarves.
