Try
www.airnav.com - it probably has almost all the airport info you need. As I'm sure you can imagine, KTEB is not cheap. Its chockablock full of corporate aircraft and the prices reflect that. Caldwell is busy, but nice.
If you can, try to visit Old Rhinebeck -
http://www.oldrhinebeck.org/ As the schedule says, they have an airshow every Saturday & Sunday in the summer. I've been to one and it was great fun, as well as fascinating. Definitely worth visiting. I don't think you can fly in tho'. We stopped at an airport about 45 mins drive away, but I'm sorry to say, I can't remember the name of it. If you can wait, I'll dig in my logbook and check.
You could also check for EAA chapters and general fly-ins in that area -
www.eaa.org. Just google the area along with fly-ins and if that Department of Transport is like our local one, they'll have a whole page on them.
