GEORGE MCCOLLOUGH spent much of Capsule Day hanging out at Philly Cuts, a barbershop in West Philadelphia that serves University City and its environs. Topics of conversation ranged from how the shop got started, how Chestnut street used to have doormen, what's gonna happen in 50 years, and the funkiest haircut given so far (a palm tree). If you only remember one thing about Capsule Day, remember this: "Philly Cuts for the 2000 millennium and beyond, cause we gonna be all that and a bag of chips."
