Practising for the famous "Nan Boat Race 2016" in Nan

Two days ago we were passing a small village nearby and saw many people standing on a bridge over the Nan River. What were these people looking for? Right, the practising for the famous "Nan Boat Race 2016". 

The first rounds will start 3 and 4 September in Tha Wang Pha (50 km north of Nan city). 

It is amazing, about 35 man in a small wooden boat on the muddy and wild Nan River. Not my cup of tea to do, but wonderful to watch.
