HOLLAND, MI (WMC) A different kind of pet shop operates at 125 E. Sixth Street in downtown Holland. It’s a place where you find pets of the 3-wheeled rather than the 4-legged variety. PET Holland has been manufacturing Personal Energy Transports—hand-pedaled tricycles–since July 2009. They are the only one of 23 PET plants in the world dedicated to the manufacture of child-size PETs. Finishing touches were recently put on the 1000th PET, much to the delight of the 100 volunteers who have taken turns on the assembly line. Instead of the usual playful multi-colored paint job, this special PET sports a coat of gold.
