Back in the 1990's I hitchhiked all over the U.S., Mexico, the Bahamas and Venezuela. I lived on the road for four years and wrote a book about it. There is a LOT of info in there, that although from 20 years ago, would mostly be relevant today. It's free on Amazon Kindle until July 5th. https://www.amazon.com/Travels-Road-Dog-Hitchhiking-Americas-ebook/dp/B01E6KGXBY/ref=sr_1_1?s=digital-text&ie=UTF8&qid=1498975283&sr=1-1&keywords=travels+with+a+road+dog
