I knocked the rust off on a solo in and out 2 night on the Tecumseh eight years ago or so, after not having backpacked for years. Missed last summer, want to get back out there again.Most of my experience is around "base" camping as it was always family oriented. I did some trekking/pack camping 20+ years ago. I required much less as I was young and required less to live. Sometimes just a knife, a tarp, and a flask. I'm too old for that stuff anymore.
I appreciate your input. Don't plan on doing the AT anytime soon, so a lot of specialized gear isn't necessary. Maybe the local KT, but gotta get out and knock the rust off first. Looking into 3-5 day/night outings.
As previously mentioned up-post, I am reinvigorated of late and plan to get back into solo camping.
