Madron, 12, of Colora, developed an innovative way to wage war against the disease.
For a $1 donation, people were able to use a sledgehammer to swing at the truck. His goal was to raise $1,000, but with help from the generosity of fairgoers, Madron generated $1,603 for Union Hospital's breast cancer center.
Madron came up with the idea for Smash for a Cure after seeing Delaware carnivalgoers bash a car with a sledgehammer.
The fundraiser is not the truck's only purpose. McMillan drove the truck in Saturday's Demolition Derby matinee. After a solid showing in the event, the pink truck adorned with images of Wreck-it-Ralph and Fix-it-Felix won Best Appearing vehicle. Madron and McMillan donated the $50 prize back to Union Hospital.
