Wow. Patrick is the size of a smaller pickup truck. They are really a throwback to 10,000 years ago or so.
You really have to see these SOB’s up close to understand that they’re a force of nature, like a tornado, hurricane or earthquake. Sure, you can kill them like animals, but absent a heavy rifle, you cannot believe how strong and bloody single-minded these things can be. And in a herd... they’re not to be dissuaded by gunfire.
Panels that hold even the biggest cattle in are like tissue paper to bison. I’ve seen them literally walk through panels and gates. Not run, not crash. Just put their heads down, push, snap the welds, pry open the horizontal pipe on the gates and push their way through. Why? Well, the grass was greener and all that. You’re out a C-note for a Powder River panel, the the bison is contentedly grazing away on the scrub grass on the outside of the fence. And when he wants back in? Don’t bother fixing anything. He’ll just push his way back in.
There was a bison outfit up near the Horseshoe Ranch in northern Eureka County, NV. They got tired of chasing after the bison when they’d break out, so they built some corrals out of 4” gas well casing (about 3/8” wall thickness steel pipe) sunk about 12’ into the ground, then they welded highway guard rail to those uprights - up to about 7’ high.
It kept them in.
Most of the time.
Neat critters. You couldn’t pay me enough to try raising them behind a fence.
