Here is a fascinating interview of a builder and teacher that talks about his experiences of living in a pop up trailer in Baja that led to his building a tiny home in Oregon on 5 acres. Living in Baja opened his eyes as to how few possessions he really needed to be happy. Living simply in Baja changed his life philosophy.
Enjoy.
