Pro-tip, build a real fence instead of a folksy one out of 3 strands barbed wire. My animals are safe, anyone's animals can be safe, we have the technology, and if I'm not mistaken a cattle rancher has a lot of spare time on their hands to build that fence. The story you've told over coffee 200 times can miss a few sessions while you put up woven wire with an electric top. Sheep people know this and everything kills sheep so why aren't cattle protected in the same way? Interesting isn't it..
