My favorite is Antelope.. Probably requires more stealth than any of the other game. Not as much cover as deer or elk, and eyes that can spot a fly on a cows butt at 800 yards....
I like hunting antelope best of all for these reasons:
weather is usually (not always) in high 60s
always observe dozens of animals
enjoy the vast open prairies with occaisional flat topped buttes
always get one or two depending on zone
enjoy hunting with our aging Remington pump in .243; sort of like an old friend
enjoy antelope sausage very much
