Yawps this weekend was crazy

So yea this weekend i was running at Aiea High School and the band was practicing on the field. They were super good, they were playing the Mortal Combat song. It was epic. So yea i was running up the bleachers and when i got to the top of one of the stairs i remembered my physics blog, so i was looking around for something. But all i needed was right in front of me. The band was practicing formations with flags and all, so my blog is about the transverse waves that you could due to the flag waiving.
