don't wander down dark alleys alone at night and you'll be fine. the usual: keep your wits about you, maintain situational awareness, don't plug your earbuds in and crank up the tunes. Stay with other groups of people if you can. Doesn't sound like you'll have a car so no one should carjack you. (And if you were planning on having a car, don't. Parking up there is a bear.)
