To my family and friends, As some of you know, I have just started my tour in the remote mountain area. Everything is going really well, so no .The land is beautiful but unfortunately it has a lot of too. I have received several emails asking what I need while I'm here .so I decided to write you all and let you know that I don’t need anything. At least not for me. I’m asking all of you to send me a few to help the local children. Let me explain. On 12 May 2009, in a small village here, 120 school age girls were by a gas leak（煤气泄漏）. Most have but 6 are still in hospital. Even though the local government speaks about the of education for both boys and girls but most of these kids only attend school for four hours a day if they are even allowed to go. They are so excited and to learn, but then have to things like being sprayed（喷射） with acid or poisoned. Most of these kids are poor and can’t a pencil, pen or even paper to write on. So my co-workers and I are planning a trip to several schools to promote and to give these kids some of the they need. That is where all of you come in. If you can, please whatever school supplies you currently have . That would be a huge help. I know how busy you are so thank you for taking the to do this and I will post pictures of this after we go. Thank you again. Todd Tucker
