Jason Brier, 7, and his uncle Joe McGrath, center, both of Kennewick, ask Jeff Bainter, owner/driver of the Captain USA monster truck, how he fits the rig in his trailer with such big tires during his visit Friday to Kadlec Regional Medical Center in Richland.
Bainter said he has a set of smaller tires he puts on to transport it.
Monster trucks, tractors, fire trucks and tanks will be at Columbia Park from 11 a.m. to 4:30 p.m. on May 16 for the Kidz Dig Rigz event.
Admission and rides are both $5. Proceeds benefit Kadlec pediatric patients and their families.
