I have a childhood memory of going on a "nature walk" with someone (in Boy Scouts? at the old Jefferson County, Colo., camp for 6th-graders?) who told us about "smart pills."
He held up a nearly spherical little mule-deer turd and told us that if we ate one, we would be smart -- smart enough to never do that again!
That memory came back when I read this item in today's Denver Post: "Elk Droppings May Have Sickened Kids."
In Jefferson County, too.
