Yes, I have done them a couple of times. They became an event at the JRTCA trials after I stopped going to those trials all the time. I entered Petie in it for kicks a couple of years ago when I was going to Nationals to judge another event. He had never done it before.......in the pouring rain, waiting for our turn and waiting in the line up outside of the barn Petie started to air scent and get excited. We entered and Petie indicated that the 'quarry' (lol) was on the right side. Judge asked me if I was ready? I asked if they were ready? Yep, dropped my dog and he flew forward and crashed into the cyclinder, cyclinder and dog disappear in between the straw bales. I yelled time. lol he won the National Championship for Barn Hunt in a wicked fast time.
It was fun, the dogs enjoy it, but we would rather got hunting to some serious quarry.
