As you get near the outskirts of a city, where you live starts to depend on who you're talking to. I live in Gig Harbor, Washington, which is about 20 minutes from Tacoma, which is itself about half an hour from Seattle. If I was talking to someone else from the area, I'd never claim to live in Seattle. But if I'm talking to someone from out of state, then yeah, sure, I'm from Seattle.
