27 miles each way, into and out of Philly. Quite convenient now that I hired my brother... who I rent a room to, and who drives 50% of the time.
Of course, the flip side is I never solidly know what time I'm getting to work or getting home. The 95 corridor is tremendously unpredictable. I leave for work an hour early, which means I'm usually 20 minutes early. But when there's an accident on 95, it could be a 15 minute delay, or a 3 hour delay - no way of knowing.
Still, the paycheck makes up for it.
