We did the same thing with the corrals that Mr Lilly's grandpa built. Patched it and used it. Patched n used....over and over....and it was kinda skeery sometimes. So we finally had to break down and build new corrals. I hated to see the old wood corral go. But it was so bad that it was unsafe to work cows in anymore. It's bad when the cows go up the alleyway, and the boards moved like ocean waves. LOL
