Since 2006, I have been one of the 300+ members in a group called "Classic Refuse Trucks", which studies the evolution of waste vehicles and collection methods. I document the equipment collecting the world's trash as I simply find its functional design interesting. I especially like to preserve this industry's history by finding the oldest trucks before they are put out of service, and gone forever.Check out my photography https://www.flickr.com/photos/trashman242/Our group's website http://classicrefusetrucks.com/
