On one acre I'd have a small off the grid house maybe a "tiny house", chickens, veggie and herb gardens, orchard and a pygmy goat or two. Right now that's all I can imagine me handling.
I've always had a thing for trees... amazing things these trees.
I been researching the idea of forest gardens. Sounds like a neat idea for sustainable food production. I first read about this in a book called "1491: New Revelations of the Americas Before Columbus ". It discussed a bit about how the Native Americans managed the forests for food production. And check out "Geoff Lawton's Permaculture Food Forest" on YouTube.
If I had an acre I'd like to see what I could do with it.
With 5 acres I'd try it on a larger scale.
There's a rock climbing shop in Seneca Rocks (it's near Almost Heaven!) West Virginia that I'd love to replicate ... everyone remembers the friendly atmosphere there, how a pot of bean soup was always ready - steaming and delicious - for hungry patrons. I'd add a small open area for stretching, a few walls with climbing holds marked with haiku-poem-routes ("Physical Graffiti"!) of all difficulty levels so everybody could "warm up" together, space to silently meditate, and space for music makers too ... :-)
Outside there'd be a nice garden and greenhouse, fruit and nut trees, chickens, rabbits, goats, etc ... :-)
Plus there'd be room for an occasional musical concert ... :-)
AND ... the name of this "Homegrown Fantasy" would be ...
CLUB CHERRY BOMB !!!
