I talk about it a bit here, but basically bought a truck and lived in the back of it for about two years. I spent a lot of my time rafting on rivers in Washington State, did a roadtrip down the 101 and spent some time over in England.
The freedom is amazing. I'd still be living that way but ran out of funds. Now I'm working to build up another large stash so that I can go do it again but hopefully not have to come back this time!
