You could probably go to meetup.com and do a search for "nashville backpackers," I assume, but have never tried that myself.
Anyway, it's a good group and we do regular trips. You are welcome to join if you like. Doesn't cost anything (some meetup groups charge dues).
Wow, Rain Man, someone else has an old Holubar sleeping bag! I bought my 5 deg. bag back in 1973 for $105. I don't know what it weights but it is heavy...and warm!!! They sold the company in 76 or so to North Face. Many fond memories with that bag.
