About 7 or 8 years ago my stepdad got out of the cattle business. He had one cow that proved near impossible to catch and keep in a corral.
She wintered with the local mule deer herd. It took a couple of weeks of conditioning her with a moving feed spot to get her to go into the corral. Snuck down and closed the gate, only to have her do a jail break and wreck some corral panels. That was one of the few times I was legitimately afraid of a cow. Another couple weeks of conditioning her by moving the feed closer and closer to, and then finally in the barn did the trick as she couldn't jump over the fence at that point.
A person can get all kinds of nostalgic about when we had cattle, but at this point I don't miss them, haying, or feeding cows at all. This guy is hilarious!
