What follows is a direct quote from this month's Marshall Street Newsletter (with which I completely agree):
Right in the PDGA Rules it says straight up that butts are litter. We should add that bottle caps are litter, too. At most courses you can’t even begin to pick up these small symbols of indifference, because there can be hundreds on a single tee, and there isn’t enough time in the day. The fact that litter’s main function is to attract more litter can make the job of an anti-litter crusader a frustrating one.
How nice it would be to possess enough wisdom to know the difference between the things we can change, and the things we can’t. But some windmills are nevertheless worth chasing, and some fights you abandon only at the risk of your soul.
I’d appeal to your better natures, but if you’re one of the butt and bottle cap flickers, you may have yet to meet your better nature yet. And threats? Well, most threats are preposterous. Much better when the unsuspecting litterer hears the woosh of a masked figure hurtling down toward him on a zip line, wrapping leather-clad legs around his environmentally unconscious head and squeezing out the magic words:
“Okay already, I promise never to litter again.”
