Yes, opening morning was a mad house where I hunted as well. At one point I saw three trucks full speed racing trying to get on herd and then guns blazing. You heard shots all day like a war zone. Saw one guy jump out of a truck and start blazing at a nice buck 100 yards off the road. He must have been shooting an auto (six fast shots) and missed that buck completely. Lots of hunters and lots of lead flying. Felt sorry for those goats.
Is this all happening on public lands or private? Are they driving across the pastures in their trucks?
No, I didn't see anyone driving thru the prairies but on the main roads when I saw the three trucks racing after the herd. It was a mix of a little public and lot of private. They stuck to the roads but were racing to get position on the animals and stopping blasting. I did observe one man guiding and one female hunter stalking a small band on foot for a good three four miles. She kept getting ready to shoot in windy conditions and then the animals would move. I watched em for a good forty five minutes by bino. I'm sure she eventually got her tag filled.
