Thailand forum

So I'll be spending 30 days in Thailand. I had everything I was expecting to do, more or less, laid out... and then I broke my arm and I leave in 5 days. I'm traveling with one friend, and we're meeting up with another whos been living in Bangkok for a few months. My buddy we're going to visit has the first 10 days planned for us in the south. After that we'll be in bangkok for four days, and then my buddy I came over with is heading back home. Originally I was going to do quite a bit of cooking anywhere I could, not just classes but I had some stages set up in some of the hotels in Bangkok as well. I was also hoping to go further north for about a week, cook and eat, and do a hill tribe trek. Since my left arm is almost useless(It still hurts but its getting better and I cant really move it much, but its only supposed to take 4-6 weeks to heal, so its kind of like rehabing while I'm there), any suggestions for ways to stay busy. I'd still like to travel north and hop around to some different towns but now i'll be doing more looking than doing. Any suggestions would be greatly appreciated.
