Yesterday I saw something odd out on the hayfield / south pasture fence. The area around the gate looked odd. I got out my binoculars and saw that half of the gate was down. I thought I had installed the gates so this wouldn't happen. Nothing like this happened over the years.
I have lag bolts up and down. So the gate wasn't lifted off the bolts. I guess the hinge on the top part of the gate must have slipped down. How? Who Knows? No cattle are in the south pasture.
I put the gate back on the bolts and readjusted and tightened the hinge. The gate should stay in place.
