When was the last time you took the deuce? Did the No. 2? Get your minds out of the commode — we're talking about MARTA's No. 2 bus, which gives you a street-level view of one of Atlanta's most iconic thoroughfares. The bus, which runs between the North Avenue rail stop and downtown Decatur, chugs through such vibrant neighborhoods as Poncey-Highland, Little Five Points and Candler Park — and picks up some of its more interesting characters. You can share a ride with the ladies who lunch at Mary Mac's, the homeless folks trying to rebuild their lives at the Open Door Community, or the always-colorful diners at the Majestic. And, from the comfort of a molded seat, you can safely observe the panorama of humanity that Ponce de Leon Avenue has to offer: hipsters, crackheads, hookers, students, transit-dependent working folks, eco-conscious office workers and, if you're lucky, a certain street person with a familiar bulge in his shorts.
