Horses...it's always something.  Just when you're trotting along really having a good time, your horse steps on himself and pulls a shoe, ripping half his hoof with it.  You get some new, really  beautiful looking hay and your horse develops an allergy to it.  You get your horse fit, sound, ready to race, and a big piece of cardboard blows up the shed row, and boom, you're doing damage control.  That's the thing about horses...it's always something.
