I have been in thailand a lot love the training spent many trips at different gyms across the country (mainly the southern islands) its an amazing but brutal sport. I had to return to the UK though the problem I found in Thailand is it was so hard to stay away from the drink and drugs especially the islands where it is so easily available.
I loved songkran but find it impossible to stay sober during it hopefully will be able to go back for it one day and do it sober
Back there october-january and can not wait love the country.
Hope things are going well
