I remember when we would take long drives when I was a kid (vacation, visiting relatives, whatever) and seeing the sides of the roads just covered in trash. Paper, bags, unraveled cassette tapes were everywhere. Over the years, I also watched most of it disappear, even in the crappier neighborhoods of Chicago. Adopt-a-highway's were prevalent and people just seemed to be more careful.
Over the last year or so, as I've driven to and fro, I'm seeing a reversion. Trash is creeping back onto the sides, some areas just positively covered. So the question I ask is 'Why'? Have people lost that pride in cleanly environment? Are the strict 'No Littering' laws not being enforced as they used to be? Or are people just crappier than before?
Either way I see it as a statement on how things are now.
