The hunt areas around Casper have decent goats, really good numbers, and tons of public land. Don't waste your money paying trespass fees in Wyoming. There is public land everywhere you go, and you can shoot goats that are just as big or bigger than the ones you will find on private land. One area you might want to consider looking at is area 48. It's very accessable, there are tons of antelope, the drawing odds are pretty good (100% for resident, not sure about non-resident), and there is public land everywhere. It's some pretty neat country too, with the Miracle Mile on the west side of the area if you want to do some fishing (and if you're willing to fight off all of the greenies).
