Now, if the world weren't already small enough already, a sandwich shop in North Beach sells "Pittsburgh-style" sammiches. I found this out because I sat on the bus next to a woman who said, "hey, I met someone who knows you. A white guy. From Ohio, maybe. Did you grow up in Ohio?" After we nailed down the Pittsburgh part, we puzzled it out as she added more clues. And then the sandwiches came up. Hot damn!
