One cold night in the '90s, the Boulder air was redolent of cow droppings. A co-worker said "you can smell the cows of Greeley -- it's about to snow." I thought he was, you will pardon the impression, full of shit.
He wasn't. It was snowing within hours. And in the years to come, I noticed that it held true -- when you smelled every cow on the farms north of Boulder, it was likely going to snow.
I went for a nice stroll around my folks' neighborhood this morning, and smelled the cows -- and now the snow's coming down. (I'm ensconced safely inside, drinking Colorado beer and eating the family chili cheese dip recipe. Life is very pleasant.)
Why is this? Why does imminent shows make cows get the Metamucil off the shelf? I've never known much about cow biology.
