As yellow jacket season ends and jacket season starts, Philadelphians get street-festive, food-festive, ethnic-festive, and parade-happy.New this fall are an indoor Oktoberfest that aims to be the region's largest, a car-free streets event that aims to recreate the vibe of last September's papal traffic ban, and a Citizens Bank Park local-foods festival that expands beyond the cheesesteak. Your belt may need expanding in kind.

Terror Behind the Walls (Sept. 16-Nov. 5). Halloween attraction boooosts attendance at Eastern State Penitentiary for the next month and a half. The last two nights are a lights-out "remix," in which visitors' personal glow sticks are the only lights in the joint. (215-236-3300, easternstate.org)

Philly Free Streets (Sept. 24). We wish it were bigger. We wish it brought back the buff Secret Service guys – and the nuns. But we're all for trying to re-create the magic that happened when Center City went car free during the pope's visit. The inaugural Philly Free Streets closes South Street from river to river, linking up with the Schuylkill River Trail, and extending to Martin Luther King Jr. Drive and parts of Fairmount Park.
