I'm in Roi Et, in the heart of the NE Isaan region. Regarding Chalabhorn Dam, I've been to many of Thailand's national park lakes/reservoirs over the years and they are typically beautiful and well maintained so I bet your footage was great. Soon I plan to get some footage at the Ubolratana Dam park near Khon Kaen. It's very nice and there are some private chalets for rent on a ridge overlooking the lake on the southeast shore. Yep, Thailand is such a picturesque exotic country that good footage locations are everywhere. I've already registered my Mini with the Roi Et police so hopefully no worries in the future.? If you're ever in the Roi Et area give me a shout and let's fly together. ?
