Thanks to Riverfest's special "Buy One-Give One" button sale on Thursday, 290 buttons will be provided to Operation Homefront.
The special promotion went from 11:30 a.m. to 1:30 p.m. in Riverside Park.
Cheap Trick is one of the acts that will be entertaining Riverfest crowds this year. Also during Thursday's special button sale, Riverfest will donate a button for every Cheap Trick ticket purchased.
Buttons are $5. Concert tickets are $20.
