Thanks not far from Udon at all. looks like a good palce to play tourist and have another adventure before the rains. Cambo sound interesting as well, but I'm not ready for that yet.
You would be hard pressed to find nicer people then Issan folks.
I found about Khmer sites on TAT and asked them to send me info and maps. They really are good about that if you just ask.
Have met a few riders from the area and it woudl be fun to share some adventure with them
Thanks
