I wish I could live in Mexico through the winter and here through the spring, summer and fall. I do also watch the superbowl for the commercials, lol. We use the thick cattle panneling for our weaning pens. Seems to work ok on ours. We have thick posts holding it up and a 2x4 lining the top. I am going to post a picture of my old shorthorn heifer and you can see the fence in the background. ~~> edited... I don't know how old your heifer is, but for cattle we usually use 4 prong high tensil barbed wire. Keeps them from pushing on it. Wouldn't use that if you plan to put horses in it in the future though. We had to run electric on the inside of it when we moved horses into it. So I guess that's an option as well.
TPBM is running out of things to say that haven't already been said, lol. I don't know... TPBM prefers western over english riding. (not saying one is better than the other, just prefers.)
