Today it cooled down to a chilly 37C from a high of 39C yesterday. I actually (foolishly) brought a light jacket with me, guess I will not be using that baby! In the videos I saw of Mae Sot everyone was wearing jackets, so I took mine, figuring this place was somewhere high in the mountains, oh well! will know better next time. Put on sunscreen 4 times so far today and drank over 3 bottles of water.
