First of all welcome to the forum! stick around and learn as much as you can as theres a lot of information here. I go to Wyoming every year for antelope but so far have not checked those units out. I have hunted many different ones by going over the data for draw odds and public land or HMA areas available. Hopefully someone with real information will jump in but that't all I have.
Good luck with your hunt if you make it up there. You will love hunting antelope if you haven't done it before already.

I do not know much about 18 or 19, but I have a nice book at home that might have some info....I will check later tonight and let you know. If not I can give you some insight to some of the areas around where we hunt.

For someone that spent 3 years in 82nd Airborne jumping out of all manner of military aircraft, my friends find this ludicrous - but... it is what it is!
Climbing stand? Yep, still scared - put me up 15' and that is about it.
Ladder stands? I am better in these - but still cautious.
Chain on stands? Used to love them, now they terrify me.
I was once ridiculed for putting chain on stands waaaay too high - some of my friends...
