I hear you.. It makes me so mad when I hear about this topic. It would be horrible to protect them because it will just cause more soil erosion and hurt grasslands. Also, when cattle step in the holes it can hurt them.
And people, and horses. One gazillion acre ranch I cowboyed on a couple years ago was riddled with holes. Too bad the wackos never will have the pleasure of having to lope their horse balls-to-the-wall to turn a herd of heifers that ran past a gate. At best, you got one eye on the ground and the other on the cows, especially after a rainy spring with extra tall grass. Kind of like running through a minefield blind-folded. One of my partner's horse stepped in a hole, went down but didn't break a leg but my buddy broke his wrist and bashed some ribs.
When I was down there shooting the critters, I took a pic of a hole that was over a foot in diameter and (due to erosion) at least four feet straight down.
It's nice to see many of Clinton's ex-NutCakes are being put back in a position of power. All I see lacking so far is the delightful Bruce Babbitt bringing my part of the country more wolves to finish wiping out the moose, elk, and domestic calf crops.
