The Last American Man" (and even for those who have), I just happened upon a TED Talk done by the man himself, Eustace Conway. It gives a great snapshot of his life and the kind of fortitude that he exhibits in his adventures.
Also, there's a chance that my own hitchhiking adventure was not the first time that I met Eustace. I have to do a bit more digging, but there's a chance he may have visited my elementary school at some point... May I introduce my new D.A.R.E. Program: Dilatory Abuse Resistance Education.
