The area around Temple is dicey, to put it mildly. You'll be fine as long as you're careful, but BE CAREFUL. This neighborhood is no joke - carjackings and shootings occur frequently within blocks of the campus, and sometimes on campus, including in broad daylight.
Drive only on main, well-lit streets and streets with campus buildings. Do not turn down any small or unfamiliar streets. Do not listen to GPS if it suggests a shortcut. Be prepared that there are often aggressive people hassling you - including pounding on car windows, etc. Be alert, including and especially at stoplights.
Unless you can find street parking on the block of the theatre, park in a secure lot (

Walk together with your friend, and do not stray from well-lit paths on main streets. Definitely do not walk a mile in that neighborhood - you could be in serious danger. Know where you're going at all times and take the quickest path. Don't have your phone out. Don't carry much cash or have valuables on you.
This is not Center City; this is not like Penn / Drexel / West Philadelphia; you're on the borders of some of the worst neighborhoods in the country, much less the city.
