D.C. Is Offering Free Canoes If You Use ‘Em To Pick Up Trash on the AnacostiaFrom now until the end of summer, if you’re in the Washington, D.C. area and want to canoe down the Anacostia River, you can book a free canoe from the city provided you adhere to one rule: You must use it to collect litter. Part of that is now this new Green Boats initiative inspired by a similar program in Copenhagen, Denmark. They get a receptacle for litter and a little picker to fish it out of the water. When they return, they are asked to help sort the garbage so the city knows which kind of trash is most prevalent. The Green Boats program, if all goes well, will be expanded into a fleet of free rental boats for everyone, all the time.
