1. My guardian pig: Great idea and reminds me of holding goats with three strands of slick wire up in Tonto National Forest in Arizona. We hung beer and soda cans on the fence and painted them with molasses. The old nanny goat would go up to the fence, lick the can, snort and shake her head and never go back close to that fence ever again. In fact, it got to be a problem because a narrow strip of grass just beneath the fence grew so high as to short the fence out.
3. The hammer trick: In Colorado we used to do essentially the same thing when repairing fence after a hard winter (a regular spring time operation). We carried a roll of slick wire with us to patch the broken fence with. We would put a loop in each end of the broken barbed wire. Then cut off a peace of slick wire long enough to fill the gap. Then we would spin the slick wire around the hammer head and tie it off. This avoided the problem of hanging up on the barbs.
Reminds me of a funny story. I had been doing this all morning one morning–all by myself up in the San Juan mountain foothills. Noon came and I backed up against a pine tree to eat my sandwich. I looked up and right there in front of my eyes was the biggest damned bull Elk I had ever seen. The sumbitch calmly walked up to my newly repaired fence, stuck his antlers into it, twisted his neck and steeples shot out of posts for about a mile in both directions. Then he just calmly stepped over it and went on his way. If I had had a gun big enough, I’d a shot him.
6. The Raptor Perch: Another great idea. The way we always handled it was to sell prairie dog hunting rights and thereby generate a little revenue out of it.
