Peter told me not to come back to Philadelphia.
"It's not here any more," he said.
I was waiting to get on the plane, and getting a last look at the palm trees and white haze of San Diego out the window.
"Then where are you now?" I said.
"Tulsa," he said. "Calls are being rerouted to Tulsa. The Philadelphia Underground is in Tulsa. Philly's gone."
"What did you guys do with it?"
"We blew it up. They put this glass dome over it. Like the ultimate gated community. You couldn't get in or out of Center City. We just got frustrated, so, you know..."
"It's lucky you told me this before I got on the plane," I said.
