i have hunted antelope twice both times took a total of 7 hours. they are not hard to hunt, just get some practice with your gun and be ready to shoot 300-400 yards. u don't need a outfitter or guide!
I agree. Hunting with an outfitter diminishes the hunt a great deal in my opinion.
"Here's my money. Where do I sit to shoot one?"
Hunting on your own as you did is the way to do it in my opinion.
