Ever had that moment with your horses? Something happens, and you think "Oh yeah, so-and-so said that might happen..." My coming five gelding sprouted a wither out of nowhere. I swear, he didn't have it this fall. Now, he is actually 14 hands! (thanks, wither!) @Rhythm 'n Blues mentioned in someone's thread that this happens around five. Guess she's right! So, here's a thank you thread. What have you learned that really turned out to be true? Who do you have to thank?
