Equine foolishness

I spent most of yesterday putting up a new fence... which the four-legged idiots have, in less than 24 hours, managed to break, tear down and pretty much make everything I did yesterday a waste of time.

How is it that four legged critters can spend three years inside a fence consisting of three strands of rusty bob-wire, but can tear down a new fence built from woven wire (field fence, page wire, hog wire, whatever you want to call it) that is topped with barbed wire that quickly? The funny part is, the fence wasn't finished, all they had to do was walk forty feet and go completely around it. If this continues, I'm going to look into a six strand electric high tensile wire fence.

Cows are stupid, but there are times when I swear horses are even more stupid.
