As bizarre as this will sound, I've actually come across a mattress in the woods during a trail ride. And a sofa, some big comforters and several other things. It was after a big storm so I think a hunters cabin was decimated and all the furnishings were flushed out/blown away by wind.
Horses walking on bubble wrap is HILARIOUS. So is watching their reaction to silly string.
Reminds me of the time when I lived in California and was driving to work on 280 and drove by a sofa that was just sitting in the middle of the highway.
I'm watching the Live Oak CDE on the USEF Network right now, and I would say this is a PRIMO example of why you do de-spooking. The wind is blowing tents down and crap all over the course, and this is *exactly* the situation where you damn well *better* have despooked your horse to where it keeps listening to you in the middle of an international competition no matter WHAT happens!

Three Figs, I have done quite a bit of "bombproofing" with my mare. On occasion she will say "no" to something. I always listen to her as I kinow she will go thru things unless she thinks something is wrong.
