#1: OnX
#2: Be sure you have road access. Call the area game warden and county road super.
#3: Use a rangefinder. Lil boogers are hard to judge distance on.
#4: Practice shooting to 300+yds.
#5: I have had winds over 65 mph when hunting in October. Plan your camping judiciously. It can be 80 degrees one day and 25 degrees the next, with 50-60+ mph winds at times. I'm usually lucky and only deal with high winds 2-3 of days per 8- day trip.
#6: Leather gloves and knee pads. There are little, low growing cactus everywhere, and are hard to see until you "find" them.
#7: Skin, quarter and cool the antelope ASAP. They are our favorite meat if handled correctly. Learn the " gutless method" if hunting far from the truck.
#8: To each his own, but I try not to go opening week. It is a zoo. By the second/third week most hunters have gone home or directed their attention to other game. Conversely, if you do go for the opener, I would suggest going a day or two before, scout some goats and be on one before daylight opening day.
#9: Don't overlook doe tags. Inexpensive and there are a lot of them! Did I say the meat is delicious?
#10: Unlike most big game animals, antelope do not seek cover, but instead prefer to see predators at long distance and then they kick in the afterburners... so for the most part country that has a lot of trees and tall brush won't be a preferred hangout for antelope. They like to use that 8x vision!
If you do your homework and spend some time on the Wy Game and Fish website and make a couple calls you should be fine. There are a lot of antelope in most all areas of Wyoming. The trick is intercepting them before they cross onto private.
Best of luck to you.
