Coming this January I want to ride from Cambodia to Thailand to Laos back to Cambodia.I will spend 3-4 weeks in each country.The bike I ride will belong to a Cambodian.Will this be doable or will the red tape be to much of a pain?What will I need in way of docs,papers or whatever?Any advice or ideas would be greatly appreciated.I am Canadian and have rode in Cambodia's remote areas.Would like to do the same in Thailand and Laos.
