I lived in Philly for a few years and loved it. The sub is really odd place, it's one of the few places where the sub just doesn't match the actual area....

Yes, a lot of people over on the sub are upset over one thing or another, but it's really not as bad as they make it out to be. If you're really that scared about moving to Philly, might I highly recommend visiting for a weekend or week.

There's plenty of places where it's recommended to avoid, but there's also really nice areas. IMO, even in the more rough areas, as long as you aren't like an asshole to everyone, you should be fine.
