I remember the day that my son, Nicholas, sat on his first BMX bike like it was an hour ago. The moments of that evening are forever captured in my mind; partially because it was my son's first exposure to a sport he would participate in and also because it marked what would become one of the most life-changing experiences I have gone through. It was a very warm Saturday evening in July 2007. My husband, Greg, and I were outside visiting with a friend and our neighbors when we decided we wanted to go do something.
