What do you consider a "trophy"? There were a LOT of good looking antelope, I just wanted a bigger one than I got last year. That was accomplished. There are a lot of walk-in areas in 72, and if you haven't accumulated any preference points, it's easier to draw in that one than one that is known for putting out larger antelope, like 73, which is right across the highway. I saw a really good one, but it was almost in Casper itself, and not in my area. I don't know if you could even hunt that close to town! I think antelope are hard to judge in the field if you are looking for one that hits a certain B&C number. If you are doing a do-it-yourself hunt, look at lots of pics. Be prepared to shoot 200 yds or more after the first few days. Bring a large cooler with you on the hunt that is filled with ice. As soon as you field dress the antelope, fill the body cavity with ice, the meat will taste a LOT better, also don't shoot one that has been running hard, that taints the meat as well. You can't drive off the 2-track trails that are there. Best thing that I can tell you is to get a map of the area, with walk-in areas shown (private, but with public access). Look at the map carefully, and then overlay the areas that WY designates for hunting areas or zones. They also have a spot on the WY Game & Fish website that tells you the % of successful draws for that area. Eastman's Hunting magazine also puts out in one of their issues what the upcoming hunting opportunities in the different states are like, hunting zone by hunting zone.
I like Antelope hunting in Wy. You see LOTS of animals, if you can shoot a distance, you 'bout can pick what distance you want to shoot the animal at, and if you're lucky, you can also drop one right next to the road (2-track) so you won't have to drag it at all! Or, you can make the hunt as difficult as you want. Glass the area, find the animal, park a way's back and sneak up to them. We saw some that were quite a ways off the road, and really didn't want to pack them out in 80* temps.
