I am such a smart ass!

Really this is a new post. The old one rotted off at the bottom and the old ladies were on the verge of a massive pasture break. The only problem seems to be that this post is about 2 inches farther away than the old one. This allows the slide bar enough room to move back and free itself from the hole that keeps the gate closed. Until we decide to drill another hole in the gate panel the two inches in for the stopper pin, the girls can wiggle the slide back and open the gate.  Thankfully they have not mastered the workings of the spring clip yet, so the chain will keep the gate closed.
