Unfortunately I'm off to renew my multi O there on the 4 th of November, stay a night in Mukdahan, then over early to get the application in.
Fined the place boring and expensive, only up side, cheap beer Lao, which will be drunk all day.
Once, rented a tuk tuk for the day, went and looked at some pile of rocks, Hindu/Buddha temple, but just too hot for much walking around.
