If this drought continues, you should hunt in a blind over a good waterhole with a good decoy. Spend a few days scouting those units and you'll be able to see what waterholes they are using, set up a blind, natural or something like a double bull before season so they can get use to it and nail a monster. Stalking a Pronghorn with a bow in open country would be a huge challenge, especially during rut when the buck has all of his girlfriends with him.
Goatalopes can see 320 degrees out of 360, so the only thing they can't see is directly behind their head. Add to that 8X power eyes and you have a very difficult stalk a head of you.
One of the most important pieces of equipment that you will take hunting is a good quality pair of optics and they take some care to give you the performance that you want. So here are a few tips.
Use some alcohol and cheese cloth to clean the lenses. I will usually pick up an extra cleaning kit from my optician when I have my eyes examined.
Don't touch the lens with your fingers. If there is a stick or a bug on them blow it off.
Use the lens covers. They are there...
