Fans were encouraged to bring their guns to a Michigan ballpark Friday night as part of a promotional event by a summer league baseball team.

“2nd Amendment Education Night” was held at C.O. Brown Stadium when the Battle Creek Bombers hosted the Rochester (Minnesota) Honkers.

Bombers general manager Tony Iovieno said that the event was a way to promote gun safety and to showcase Freedom Firearms, the area business that sponsored the event.

Iovieno said extra security was planned. Those with guns got a wristband and weren’t allowed to purchase alcohol.

The Bombers provided free trigger locks to fans. The team is part of the Northwoods League, which is made up of college players.
