Not I, watched it for the first time at our state fair this year! Really awesome! I'd love to do that, but the horses my in-laws have are getting too old for that stuff lol. Might have to buy a few younger horses.

There are a couple of clubs in Iowa, they may have a new shooter clinic with already trained horses. Here is a link to a video from a clinic in South Carolina. https://www.youtube.com/watch?v=Di8sjxWDvy8
