Glad you finally made us aware of your neat-sounding self, OrionsBelt. You really ought to get to know Wordwind--sounds to me like you're two of a kind. (That is a compliment.)
Well (man, you-all are making me blush right and left, today!)--it is just possible that I am the horse "expert" of all the board members. I'm not recalling anybody saying they're familiar with them. BUT--even if I happen to know more, I am not an expert! I'm sure Sparteye and you have it right--it's an exaggerated image. Though for some unknown reason, I get an image of a horse eating so much that the food piles up and up, until it chokes the horse from the INside. Weird, I know.
