Fishfinder,
I have an friend who did the woodsy thing. He started while in college. He changed locations a few times, Wyoming, Idaho, Wyoming, Idaho. He did it while in college, complete with building his own cabin. Admits he did not do a very good job of any of it, especially college. Lots of things tugging back and forth. More than one marriage. Now he lives in a conventional house, burns wood when he wants, showers regularly, has a job, hunts not to feed himself, although it does supply his meat. He gardens, keeps horses.
He admitted that having to hunt to feed himself conflicted with lots of other things and made it work.
I like the advice of shutting off the power and water, not eating from the store for a while before you stap on your loincloth for good.
I also think some now about contributing to others and less about living as suits me best.
It is a fun thought however. I like to hunt from camp and not have to drive. I like sleeping in a tent, cooking with real fire, etc. A week and a half in elk camp takes the shine off the dream a bit, and I am ready for a regular shower and conversing with all of you!
I pray that college goes well for you.
