I think it's brilliant you got to spend time on a farm, that's something I would have enjoyed =)

Horses, unfortunately. It's the dust in their coats, I think, or that's what I've been told is the probable cause. I was never any great shakes as a rider, but I could stay on, and the people at the trekking place my friend and I went to recognised us when we went back the next year. They were like, "Oh, you're an experienced rider and you know the route." Gave me a 16 hand horse, my friend a pony, and sent us off by ourselves *grins* It was fun.
