I always wanted to live a homestead off-grid lifestyle but I know my wife would not be into it and I love my Martial Arts School business that I'd have to give up.
But...
A few year back, I decided that living off grid is a continuum and nothing is stopping me from doing everything I can in the suburbs to get as close as possible. It's amazing how much food you can produce on a 1/3 of an acre, we have 17 fruit and nut trees, hunt for meat, and I even compost my humanure even though I am hooked up to a sewage system.
