I am not planning to live out of my car while on my five month road trip like this guy did while bootstrapping his start up. But his determination to spend as little money as possible to start his company is impressive in a weird way. His Quora write up includes a bunch of pictures that show how he was able to manage such a situation. Inc Magazine even wrote an article on his experience.
The guy really thought everything through - or at least fumbled into a working situation. What I found most interesting is that he did it out of a Honda Civic and not a minivan like some people consider doing.
Hotels, Airbnb rentals, and friend's residences are the way for me to go. Particularly since the old S2000's seats don't recline.
