I was riding a young stallion whom I'd just started a few days before. To give him a break I decided to take him out of the yard which was fenced in. I dismounted and opened the big gate and as I turned to set a rein on his neck, the rein fell from the bit. OK, he doesn't know that, so I reached for the other. Just as my hand touched it, #2 dropped. He knew in a hearbeat and was out the gate like a flash. The novelty wore off after about 15 min then he came to me, I'm sure laughing at me. Anyway, lesson learned. Now those screws are either nail polished in or I punch two more holes and lace them on. I don't trust snaps either and will remove them.
