The Exchange Family Resource Center in Janesville has a lot riding on this weekend's Monster Machine's in Motion. Organizer Mark Robinson says it's the non-profit's only fund raiser. The Center helps provide information, counsel, and education to help make families stronger. The event itself allows all ages of children to ride, and even operate, the large earth moving equipment. Monster Machines runs from 10:00 a.m. until 3:00 p.m. Sunday at the corner of Wright Road and Delavan Drive in Janesville. This is the event's 12th year.
