When I was in graduate school, my wife and I bought an affordable house in a neighborhood with a big factory next door. It was otherwise a lovely place, and so my morning jog often took me up and down the rural roads around the factory. On every road within a kilometer of the factory, the roadsides were littered with beer cans. On one particularly early morning, I was running when the late shift got out, and I watched somebody finish work (around 6am), get in their truck, pop open a beer, start driving, and then throw the can out the window as they drove past me. Given the quantity of cans on the roadside, this probably went on for years.
