It's summer in my hemisphere. That means (amongst other things) that I'm suddenly driving over a lot of empty plastic bottles! I've started giving myself points every time I hear the loud crunch. But really? Do they need to be rolling around in the street? I think we should let our kids bowl with them instead. Then recycle them please Chicago!
