WICHITA, Kan. (KSNW) — Families spent their Sunday at Riverfest competing in the cardboard regatta.

They had 90 minutes to build a river-worthy vessel with cardboard, duct tape, pool noodles and a box cutter.

“I think it’s a great idea because it really brings people together to try to do something,” Greg Alexander said.
