One thing that complicates the train-travel to and from Philly is that where I will be staying, I have no parking space. That means quite a trek from the apt. to fetch car. Getting back again there is not only the late-night parking at the train station to consider (in a neighborhood I do not now know), but the late-night trek from either of the two inconvenient, unsafe parking areas I know of near the apartment. When you add my physical limitations and weather concerns, it's a bit iffy. :~)
