You drive by them on the side of the road, and never give them another thought. You notice some are different, but then your attention goes back to whatever's playing on the radio. Sometimes, you've even mowed them down in cold blood on a racetrack.
They're traffic cones. And it's time you paid attention to them.
You can find out more at the Traffic Cone Preservation Society. Spend some time getting to know these fascinating creatures. I'll bet you didn't know that they've evolved over millions of years, that there are numerous species, and that some are even endangered. You can even join the Society and help to make others aware of how important these cones really are.
