Bruce, sounds like a bumper sticker.

I grew up in the country and was a veterinary technician as well (after growing up). I also have never eaten a dog turd on purpose. I've probably consumed accidental poop though, because it's everywhere and you don't develop an immunity to parasites. Plus, I had a dog and played in the grass. I never had roundworms to my knowledge. I think the major dogs-at-festival issue would be bites.
