Rigsy, if I remember you are in Korat, I can suggest dropping in on one of the shops that deal with motocross as they will be able to provide some info. I had previously done the same when I wanted to go see a race and I was directed out the 205 road to Chaiyaphum one Sunday, in the middle of nowhere there was a track and a big event, few foreigners racing also, would never have found it otherwise. Check the following: if you go on to Suranarai Road from town side, heading towards the Dusit Princess hotel there is a meachanics shop on the left hand side, easy to spot as there are always a couple of YZF's sitting outside, ask in there as they will know the up and coming events. Hope you get some info. Cheers, Kev
