The event will begin at 6 p.m., and conclude at 9, and will feature a live concert, a cruise-in car show competition, a Kids' Zone, giveaways and more.
"The community has been at the heart of our business since we opened our doors in 1911," Our Community Bank President and CEO Kurt Rosenberger said. "We felt that the best way to say thank you was to hold a big celebration and invite everyone who wants to attend."
The big highlight of the event will be a live performance of the East Street Band. The five-piece modern country band from Bowling Green, Ky., has been entertaining large crowds throughout the Midwest and Southeast since 2007.
The band has shared the stage with national acts, including Justin Moore, Josh Thompson, Chris Young and Rhett Akins and won the 2010 Battle of the Band contest at the French Lick Resort.
From 6-8 p.m., vintage car and truck owners are invited to participate in the cruise-in car show for a chance to win one of four prizes.
In addition to the coveted President's Award, entrants will be eligible to compete for Crowd Favorite, Farthest Traveled and Oldest Car prizes.
The Kids' Zone will feature all sorts of free activities for youngsters, including a bounce house, an inflatable slide, face painting and balloon sculptures.
"Everyone is invited to have a slice of our 100th birthday cake," Rosenberger said. "We'll also have a good vendor and lots of great giveaway items."
