Here's the story from www.wwlp.com:
SPRINGFIELD, Mass. (WWLP) - It was an unusual site on several main roadways in Springfield Sunday afternoon.
One after the other a steady stream of tow trucks headed to the Shriners Hospital for Children in Springfield.
About one hundred of the trucks made the trip to raise money for the hospital. It is a special cause for many of the drivers.
"As towers we see so much carnage on the roadway and we really feel this is a way to give back." said William Johnson of the Statewide Towing Association of Massachusetts.
Organizers of the fundraiser expected to raise about $10,000 thanks in part to a member of the towing association who agreed to match all donations.
