The problem is its NOT that easy to know. West Baltimore doesn't just = dangerous. Walbrook Junction might be rough at times but the neighborhoods of Dickeyville, Franklintown, Mt Holly, Ten Hills, they're quiet and mostly very nice. Same with Poppleton and Pigtown and Hollins Market. You don't know which neighborhoods are rough or dangerous, or if they're just that way at certain times of day, until someone tells you specifically which neighborhoods to avoid or you've lived here long enough to figure it out. Or you're lucky enough to exist only in the L.
