Hunting bison is like hunting cows in a farmer’s field. The rest will only run a little ways when you shoot one.
You’re thinking of prairie chickens. You shoot one of them and the rest come running to see why it is flopping around. If you put the dead ones in your truck it’ll smell like farts all the way home so put them in the bed.
That is why they imported pheasant because they’re more of a challenge.
