Personally since I am a big time loner already, I would probably just wander solo from place to place in a endless cycle. I wouldn't be a bad ass or anything just a wanderer. I may make occasional friends on my journeys, but I would drift out of their lives as quickly as I drifted in.
I donno to me the solitude of walking alone in some desert wasteland seems kinda peaceful, and would be a really good way to clear your mind. Finding a survivor colony of people doesn't interest me. Why would you go straight back to the chains of society right after you have been freed from them?
Then again maybe I have watched too many movies :/
