It attracts bees. I absolutely guarantee that I've got more bees in my yard on any given day than the entire rest of the neighborhood combined. I can only think of one other house that doesn't poison their lawn all year 'round. The bees (and birds) all come to my yard.

I drive through the yard to drop off firewood, sand, bagged topsoil, whatever. It recovers. So the "stay off my lawn" thing is really just a loud joke, mostly for my wife's benefit. The subwoofers in the go-carts easily prevent the kids from hearing anything I'm yelling.

And what's up with the go-carts anyway? When I was in high school it was all about muscle cars! My minivan can blow the go-carts off the line. They just don't have mufflers on the go-carts so they sound loud, but they can't get out of their own way.
