NJ is a couple of hrs by car. All you need is gas money If you are near Jersey City, let me know.
My daughter and her husband live North of Princeton. I get there a few times a year. It's actually a pretty nice area, but with a very high cost of living. I can't always drive because of my stupid disease, but I'd really like to try the train from Harrisburg to Princeton. It costs 40 bucks one way though. How does Germany get by with relatively inexpensive train fares??
