I have just returned from a month in Thailand. I travelled - unfortunately on 4 wheels - from Mae Sot to Mae Seriang to Mae Hong Son and then across to Chiang Mai (excuse spelling I can't find my map).
Anyway, the road up to Mae Hong Son has over 1800 of the most perfect corners I have ever seen and the traffic is light. I was drooling and wishing I had my bike.
I thought you might like to know, I will be back there sometime for sure, it's worth the ride!
Four wheels moves my body.
Two wheels moves my soul...
