Heiderschiedt had four different types of cancer, he said, including lymphoma and uterine and ovarian cancer.
"Everyone has been involved with cancer," Boyd said.
Boyd's wife, Lauretta, died 19 years ago at the age of 50. She lived for eight years with cancer.
"If it didn't happen to someone in your family, it's happened to a close friend," Jaeger said.
Proceeds from Jaeger's truck show and the raffle tickets sold at $10 a piece for the purple truck all benefit the American Cancer Society's Relay for Life. Ticket sales began on May 3, and one year later at the Midwest Pride in Your Ride show, one ticket will be drawn for the winner of the truck (or $18,000 prize, whichever the winner prefers).
After this year's show, Jaeger's show was able to donate more than $47,000 to the Dyersville Area Relay for Life.
The truck was painted purple to honor cancer survivors, Jaeger said. And 29 different cancer ribbons grace the side of the cab. For more information, go to www.midwestprideinyourride.org.
