Upper Allen Township and Keystone Marker Trust, a non-profit organization, have collaborated to restore the historic Shepherdstown Keystone Marker located on the Gettysburg Pike.
Each NHL game features 60 minutes of playing time, broken down into three 20-minute periods. The league also mandates a 17-minute intermission after the first and second periods to flood and ice and provide the players with a rest period.
The length of time of this round is dependent on the type of hockey that is being played, but can last between 5 and 15 minutes. When there is a tie at the end of a sudden victory, players will participate in a penalty shoot out.
