Hi Dweste,

I would go the self-sustaining retreat route. I saw a book a LONG time ago called "5 Acres and Independence" if I remember the name correctly. I'll look around a bit to see if I can find more information. That looks to be the best way to go based on the constraints you have listed.

Cheers,
LW
