This afternoon when I left the Klong Toey slum hotel I was loading one of my 50 pound bags (the bag with my dump boots and hats) and felt a pain in my back. I knew something was wrong right away. I have been limping about Bangkok ever since. I do not think it is a serious injury just a pulled muscle but all back stuff is problematic especially when I will soon need to carry my 40 pounds of camera gear in the dump. I hope my back does not limit me. I worked out so much trying to build up my core when I was in Canada and 8 days into my trip I tweek a lower back muscle, this sucks!
