Hi Kimberly,
I looked and there is a Tenn VolunTear group on TearJerkers (kind of a sister forum)
http://www.tearjerkers.net/forums/
They have some campouts listed for this year in TN.

You will probably have to sign up to view these, but it's free and on the bright side the forums are a lot alike to get around in.
FYI, the Southern Appalachian Chapter is having a May event, SPRING FLING AT THA HOLLER *2009* May 15 – 17, 2009
Raccoon Holler Campground in Glendale Springs, NC I don't know how far that is for you, but it is in western NC, which is practically in eastern TN.....
Hope this helps.
