Cleaning up the city, one trash can at a time

While perhaps it should just be innate to throw something away in a trash can and not just out of a car window or on the floor, this makes it more likely that the trash will actually find its way into the trash can. I wish we had these at the school where I teach! I'm sure my students would be scrambling to clean up the room after class and throw away their trash! Now we need one for recycling....
