i was looking into trainhopping once, and honestly, it's just one of those things where I think you had better be ready for some rapid adaptation to the environment or else you're in a dumb situation. The road has plenty of dangers, but if you're one of the rare few that finds their groove- I think it's probably a better living than most get.
Plus, train punk is a fun look. What it is with some of those bastards being so fashionable when living out of a garbage can I'll never know, but I am obviously missing out on something.
