I think you're confusing Thailand with Laos,
Things people did there
nope, I don't confuse the two at all. King of Lao has been dead for a while as the commies sent him to re-education camp and he never returned. Mines and unexploded ordnance is an issue in Laos and not in Thailand. Anyway, Luang Prabang is a good place to visit, but make sure your insurance covers medical evacuation.
