Few days ago on Mae Haad beach we met a motorcycle travelers from Argentina. We met them a couple month ago in Bangkok.
Julian and Lorena with lovely dog Trico travel on motocycle (Africa Twin 750 cc) since 2002 non stop.
They travel around the world on very small budget and happy to get any support.
This is their web blog http://porsiemprelamoto.terapad.com/
Good luck guys!
