I love the nomad lifestyle, in the US being a nomad was easy especially if you have a big vehicle (I had a bus) because once you pass the suspect screens that the police implement to get a green light in their system you are no longer harassed. Here in South America it is different most foreigners are treated very well backpacking or with a vehicle, if you know the language and present yourself well. It is very hard to be broken if you have all your wits, desire, motivation and determination, a person can go indefinitely with a laptop and a backpack without ever stopping or until you complicate it.
