So, my son was helping me hitch the young filly. I have been working with her single, but all line driving. We hitched with her mate to a sled. The sled was parked on the gravel drive. Once I started the team, things went very bad, very fast. The filly didn't like the sound of the sled on the gravel. Usually that is no big deal and they settle down in a matter of a few yards. This time, however, we forgot to snap her outside line! Rookie mistake, but only being able to make a right hand turn at a high rate of speed is hard on an old man's underwear!
I got the team stopped fairly quickly, thanks to her teammate Duke. My son went to their heads while I unhitched. That was when we discovered the unhooked line.
We fastened the line, then I drove them around for about twenty minutes without any other problems. I will have her back in the sled in a couple days, then on to other things with her. I was glad to have my son helping and Duke with her. It happens to all of us folks...Stay Safe!
