We did go to Ubolrat lake, about 50 km North-west of Khon Kaen city. On the east side of the lake is a mountain range with with "Nam Phong" National Park and "Hin Chang Si" viewpoint. Along the lake are a 3 small villages and there are rice-fields and cattle farms. And also "Bang Seang 2" and small peninsular with many small restaurants on big bamboo rafts anchored along the shore. That is where we had a early dinner with fried fish, fried rice and BBQ Pork. That is also where my wife dropped her sunglasses in the water. But the owner of the restaurant called her son and he did jump in the water and recovered the sunglasses again. A great "Only in Thailand" moment! After that we did go to the Buddha viewpoint to watch sunset ... walking up a few hundred steep steps! I am really too old for that, next time I will just drive up!
