I was homeless for a while, purely by choice. It was very nice. I lived for a while in a van (yes, down by a river!) with a friend. We rode our bikes whenever we wanted, we made a few bucks fixing bikes and things, and ate lavishly with donations from the farmer's market. After a while, we started getting other opportunities, and our time of freedom ended when we went back to the default world. But I still remember it with fondness, not always easy, but our situation meant we were able to be happy.
Nice stories. If I ever see a fully-faired cyclist on an empty road, I'll splay myself out like a starfish as well.
peace,
