Practice for the Sheridan High School Football team as well as all Wyoming 4A teams started yesterday. Chris Prosinski Football Camp: Many future hopefuls were on the field to see what they could learn from a former pro. The 4th annual Chris Prosinski camp took place yesterday at the Buffalo High School Auxiliary Fields. The camp was designed for those in grades one through eight, and a number of Buffalo High School football players and coaches were on hand to help out. Prosinkski is a 2006 Buffalo High School grad who helped the Bison win 2 state championships and he is the 2006 Milward-Simpson Award Winner.
