Does anyone have a good knowledge about traveling back and forth from South Jersey to PA?

You're pretty much screwed my friend... The good old Port Authority isn't going to allow you to cross the river without paying for it. The only suggestion I could make is to move into PA or get a job in NJ. Perhaps you could even ask your employer for some sort of credit. Even perhaps asking to change your hours so you can shorten your work week from 5 days to 4 - which a lot of companies are doing right now with the gas crunch. Sure makes me glad I work from home now!
