Antelope look like you can just drive around until you see the one you want, jump out and shoot it. That is a limited success method.
If you really watch Antelope, you can see your way to them. I find looking off tall bluffs and figuring out how to sneak down to them the best way. Even Antelope which look like you can drive up and shoot one will be better hunted by finding a way to sneak up on them from down wind.
I share this tip because the right Antelope, is the one which is well protected by the lead doe from easy hunting.
Observation, walking and patience are the key to success.
Optics, rangefinders, long range heavy rifles and strategy will pay dividends!
