Welcome to the forum. As Pikey and I have already responded to this same post on ThaiVisa I won't repeat myself. If you go to the Board Index, look at the section on Road and Trip Reports/Other. You will find quite a bit of information there.
It appears I put my foot in my mouth again. The above post appeared shortly after Pikey and I advised a poster on ThaiVisa to come over to GT-Rider for some advice. The question was almost the same. After some emails I learned that "brfoster" is not the same poster on TV. sorry for the assumption. Questions answered via email. Cheers. :thumbup:
