At the Inner Harbor, the city will have its annual fireworks spectacular.
Parking meters will be free on New Year's Day.
And, most importantly to Midnight Sun readers, many Baltimore bars will stay open past 2 a.m. (not that the MTA got that memo.)
In the interest of service journalism, here is a working list of those bars that are extending operating hours.
Most places don't have a set closing time - when called to confirm hours, bartenders usually answered with a variation of "whenever people stop getting bombed," which is 4 a.m. (Ale's Mary's) at some places or 6 a.m. (Dionysus) at others, depending on their clientele.
Several bars will even offer complimentary champagne toasts, while others - like Brewer's Art, for example - will just be open their regular hours. B&O American Brasserie is staying open past 2 a.m. for an after party, but all tickets have been sold out.
New Year's Eve is the only day of the year when bars can stay open past 2 a.m.
Bars can do this thanks to a state law that applies only to the city. Stephan Fogleman, of the Baltimore city liquor board, explains the law's history here.
Bars closing at 2 a.m.: Pratt Street Alehouse, Mama's on the Half Shell, Funky Buddha's bar, Explorer's Lounge, the Dizz, Birds of a Feather (closing at midnight), Brewer's Art, Nacho Mama's, Charles Village Pub.
