Julie,
My chapter advisor is a member of the NJ Alumnae Club. I know they're a fairly small group, and I'm not sure how often they meet. I may have their contact info somewhere at home, but if not, I will ask her for it when we have EC next weekend. There is a very active Junior Circle in NYC, however, and I know a lot of sisters in north Jersey who attend their events. Their website is
http://www.agdnyc.com. The only collegiate chapters in NJ are Seton Hall, which is in north Jersey, and Stockton, which is in south Jersey. If you want to travel to PA, the St. Joe's chapter in Philadelphia, the Lafayette chapter in Easton (my chapter!

), and the Lehigh chapter in Bethlehem are fairly close to NJ.
Let me know if you want any more specific info, and I will see what I can do. Good luck with your move!
Loyally,
Donielle
