I haven't seen Antelope reacting to scent over vision in over 55 years hunting them - with one possible - exception. So I don't treat the hunt like a deer or elk hunt.
Same here! I watched a buddy smoking just before he pulled the trigger and successfully harvested a doe and a buck.
ADDED:
I have a couple of instances while bowhunting. These were 10+ years ago, but worth sharing.
1. I spotted a lone buck about 400 yards away. I crawled, on my knees, duck walked, etc., to get close to him for nearly an hour. I got close to him about 75 yards away, just to get busted by a herd of 50 or so running behind me and heading towards him. I still had fun, though.
2. I watched two separate herds ~500 yards away with no chance of sneaking up on them. I was observing where I had a wall/cliff behind me; the sun was also on my back. It was 0830 in the AM, my normal snack time, so I pulled out my PBJ sandwich and might as well watch the show.
I learned something while observing one of the herds. The dominant buck was clinging near the lead doe. The dominant buck allows the other bucks to chase the other does but not with the lead doe. I learned later that the other bucks were doing the dominant buck a favor. They do the hard work, and then the dominant buck does his thing—I think it's brilliant.
Anyway, the best part was that the lead doe and dominant buck somehow made it to me ~ at 30-40 yards. My heart was pounding with excitement, especially when the doe bedded. I waited for 15-20 minutes to have the best opportunity for a shot. Oh, by the way, my legs were cramping, too. The buck never knew or cared I was there. The lead knew there was something but could not make me out. The lead doe stared at me every time I had a shot on the buck, and I could not move. I have an either-sex tag and should have taken the lead doe, but got greedy and ended up with nothing. The buck was probably around 16-17 inches. Nonetheless, I had a blast.
