The scariest cows I ever encountered (and yes I'm a city boy from NY, NY) had big horns and they were running loose on the sand by the Kelso dunes in the Mojave desert in CA. It was very hard and slow slogging through that soft sand, but somehow those big guys were able to fly right over it. I thought that if they decided they wanted to eat me I'd be a gonner.
This goofy thread reminds me of a Gary Larson cartoon.
