We’ll do anything to serve our readership here at DCist, including taking up valuable Internet real estate to inform you of yet another free coffee giveaway from a giant national chain. This time up, it’s Dunkin’ Donuts, the corporate force behind an inexplicable love and devotion for so-so baked goods and decent-if-not-amazing coffee that is buried deep inside the heart of every Bostonian. No one understands why, but those wacky New Englanders, especially the ones who no longer live in New England, can’t seem to get enough Dunkin’ (or stop telling us about it).

Dunkin’ Donuts, the largest coffee and baked goods chain in the world, wants to help customers put winter “on ice.” On Wednesday, March 21, the official first day of spring, all 103 Dunkin’ Donuts restaurants in the Washington metropolitan area will participate in Dunkin’ Donuts’ first-ever all day, nationwide “Free Iced Coffee Day.”

The bad news is there aren’t really that many Dunkin’ Donuts in D.C. — we can only find a few — in Foggy Bottom at 616 23rd St., in Dupont at 1511 17th Street NW, in Chinatown at 6th and F, and on The Hill at 801 Pennsylvania Avenue. The good news is they’re serving up free iced coffees for a full 24 hours, and the offer is good at every single location, including those in Maryland and Virginia. So go forth and caffeinate.
