The fall sports season opened Monday under mostly sunny skies. Football, field hockey, soccer, cross country and golf teams held their first official practice — or practices, as was the case for the Cony football team.

The high school sports season opened Monday, beginning a fall that brings the biggest change to Maine high school sports since the open tournament experiment in 2000. High school football expanded from three classes to four. With that expansion, comes the formation of a football league that promises to provide marquee matchups every week.
