Best, leather halters. They had a selection of sizes. I also have gotten plaques with the class name and placing, and of course, money is always good too. I’ve also always thought a baseball cap embroidered with the show info would be a good prize, since most are one size fits all.
Worst is when I ‘won’ a stack of used horse magazines which were the local free ones, and about 300 dover saddlery bumper stickers. It was literally a box full of stickers. I had no idea what to do with them.
I also once won a blanket that was embroidered with the show name, but the blanket was like maybe 3x3 feet in size?? It was odd.
