For all you sport bike riders there are (quite) a few really good potholes on the main road(s) from Mae Sai - Chiang Khong. From Chiang Saen - Ch Khong it's considerably ratty & potholed the first half before Kiu Khan. The same from Mae Sai - Golden Triangle, lots of small potholes, but not as wide or deep as the Ch Saen - Ch Khong sector. I know because the happy go lucky girlfriend singer (HGL G/F S) hit quite a few of them in the car. It's funny how they go (drive), see a big pothole, focus on it & then drive right into it. The same as hitting all the cats eyes down the middle of the road when overtaking. It's only after some repetive coaching from the other front seat driver (me the pax) reminding her to only look at the pot holes, but watch the spaces & drive there. The same in traffic, don't follow the vehicle, but watch the space. Usually after 20 mins of gentle coaching she gets into the drive routine & we're away having loads of fun. It's almost as enjoyable as riding the bike! Oh yeah on R1129m the Ch Saen - Ch Khong road, as you start the "swooping ascent" to Kiu Khan, there's a lot of sand on one hidden left hand bend. Back off until you're 3/4 way up the hill, & past the sand! In Chiang Saen, somewhere I have not stayed years, we "discovered" the Sanboonmar Resort. The asking price was 800 baht, but when I queried this, the lovely owner knocked off 300 baht if I did not have breakfast. We skipped brekky & were happy with the 500 baht room, cable TV / Air Con / Clean bathroom with strong hot water. Worth checking out if you're in the area. (But I wonder that a 300 baht breakfast would be like?) We also found the best food (fish) at the Krua Chiang Saen riverside restaurant, slightly upstream of town & opposite Gin's Guesthouse. 390 baht = 1 BIG steamed fish + 1 Yam + 1 Vege dish + mixers for the Jameson's Whisky. Also spotted on the road was BobS leading a couple of 250 Baja riders around; & as BobS found out no 95 octane at the Shell gas station in Mae Kachan. There's also no 95 Octane anywhere in Fang, but the tip is head north of Fang, about 3-4 kms & there's a Cosmo with 95. But there's 95 in Chiang Saen. In Chiang Khong there's none at the PTT south of town, but is at the mickey mouse pump, on the town ring road, (same street as the CK Resort.) Take care, ride safe & enjoy.
