Hi Heather,
I am a bit in the same boat as you. Single, mid 50's, I'm living with MS (so tossing hay can't be done on a regular basis), but I have no children. I've only ever gardened on .25 acre (and just a small portion of that), 8 acres sounds like enough and too much at the same time. My 'end game' vision is a 'family compound' with plenty of 28–38-year old's to support and be supported by. I keep looking in southeastern US, namely NC, GA, & TN. I would love to have a husband in the picture during this journey but realize it may not be in the cards. My preference for livestock would be chickens and goats and LSD, though I've had pet rabbits in the past. I also struggle with what value I'd bring to the kind of community I'd like to be a part of, I can jam/jelly and learning to pressure can, I seed/plant/weed/harvest, learning to make vinegars, pickles and fermenting is on the list. I'm good with finances, a recycle and reuse type of Gal, seed collector, and stick propagator ...LOL, if I could afford what it took to be off grid, I'd probably give it a go. Thanks for starting this thread, I hope all of us reach our goals.
