This. Middle-aged men (of any race) in suits? I'd walk right through them. Young men (of any race) in ill-fitting athletic gear with surly expressions who all stare at me as I walk up to them? Avoid. Even if I'm not going to get mugged, I'm at least going to get hassled, even if I'm in a lily-white neighborhood in a lily-white city in a lily-white state. Teenage boys have something to prove, and it's usually pretty stupid.
