The last weekend, I associated King monkut university of thonburi's activity. It is first traditional bike. While I go to university, I met many people which they riding our bicycle go to join with me. When I arrived, I saw people about one thousand persons. They weared orenge shirt together with thier bicycle. I feel very excite thoughtout of the trip. All of distance is seventeen kilometer. Sunlight and soft wind made me very fresh and happy. Thanks a lot for Kmutt university, which create good activity. I think, this trip is good for health and they should create good activity every years.
