1. Fete Day at Elfreth's Alley

The Buzz -- Take a walk back in time during Philly's annual Fete Day celebration, which is held on historic Elfreth Alley, the nation's oldest residential street. During the Sunday event, folks in traditional Colonial garb stroll the cobble stones and conduct their affairs like they would have done in 1702. In addition, many of the Alley's historic, 300-year-old homes are open for public touring, making Fete a rare occasion, indeed. The ticket price for the home tours includes complimentary food and drink, and Fete proceeds go to benefit Elfreth's Alley Museum and its many educational programs.
