Thanks Aha, that's the best info I've received so far. As I remember, the guy I met briefly also mentioned they sometimes meet up for coffee so things are now clicking into place. Until a few weeks ago, I used to meet up with another Aussie guy for coffee a few km back along the road to Roi Et but he has moved away. Plus 2 other Brits but they are only around every few months as they are both still working. There are no others until nearer PP. Ban Kham Hai also rings a bell and the guy I met maybe lives there. I'll probably call in at the Amazon place next Friday. We actually live 12 km the opposite direction from PP but only 15 minutes now the roads have been improved -- slightly.
Thanks for the invite to Roi Et. We'll be there in 2 weeks, but as soon as I get my Visa extension business completed, we'll be off on a 4 day break towards Loei Province.
