I first learned about Moxie Marlinspike when I found TextSecure, his open-source app for encrypted text messages. More recently I stumbled upon his website, and there I found some amazing stories about sneaking into movie theatres, sailing around the world with no engine, and hitchhiking / riding freight trains across America. I didn't think that such adventures were still possible in today's highly regimented world.
At times I, too, have longed to show civilization the finger, to go live somewhere far away and be autonomous and self-sufficient. Unfortunately, these wishes have only manifested themselves in a few angry, solitary bike rides off into the wilderness. Every time I contemplate more interesting adventures (like jumping a fence to where I'm not supposed to be), I remind myself that I am here on a visa, and that even a slight misdemeanor could be sufficient excuse to kick me out of the US and never let me back in again.
Moxie, on the other hand, has no qualms about confronting authority and going his own way, even if he gets burned once in a while. I really admire that.
