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 NHL attempts to keep games to a reasonable length, as most fans do not want to sit in the stands for an excessive period. During the 2003-2004 season, the average NHL game lasted two hours and 19 minutes, which remains significantly lower than the two hours and 36 minutes that NHL games averaged in 1986-1987.
