Nutter FoundationDerek Fechtner says he might want to be a firefighter when he grows up. Or maybe the 6-year-old Woodland boy will become a bulldozer driver. Or maybe he’ll be an ambulance paramedic.He and thousands of other local boys and girls got the chance to test drive their dreams over the weekend at the annual Dozer Day event, spread across 30 acres at the Cemex/Fisher Quarry in East Vancouver.This was the eighth year for the event, which unites big machines and little kids for charitable purposes. It was coordinated for the fifth consecutive year by the Nutter Foundation, a charitable arm of the Vancouver-based Nutter Corp. heavy construction firm.Aimee Gebarowski, a foundation employee who, along with Renee Nutter, spends nearly six months organizing the three-day event, said there are several reasons behind Dozer Day.First of all, it raises a lot of money. After last year’s event, nearly $100,000 was donated to three dozen groups that directly benefit local children, ranging from larger organizations such as Doernbecher Children’s Hospital and the Vancouver School District Foundation to very small causes such as the Klineline Kids Fishing Derby.
