Wyoming has a great deal of public land, something over 70% I believe, and anyone can hunt it any time without permission. In addition, many landowners will allow you to hunt on their property if you just ask. Antelope are easy to find and in some areas they are, quite literally, everywhere you look. I would suggest you study your maps carefully, find an area with public land, go to the Wyoming Game and Fish website for further information and applications and have yourself a good time. Done right, the hunt won't cost you any more than the price of gas to get here, the cost of a tag and however much ammo you shoot up. Good areas to look into would be the area north of Casper and on the east side of the Big Horn Mountains and down in the Red Desert area south of I-80 in Carbon and Sweetwater Counties. By the way, there are no protected "subspecies" of antelope in Wyoming. You do need to be able to tell a buck from a doe, however.
