Vikings fans can gather this Friday to sound off and practice their battle cry in preparation of the upcoming season at the Spam Museum from noon to 3 p.m.

The public is invited to join the Vikings as they celebrate the start of their season with their “Sound the North” tour featuring the original Gjallarhorn.

The Gjallarhorn is sounded at the beginning of each game to signal that the Minnesota Vikings are coming. It will be on display for photo opportunity for all fans.
