I did just that in 2003, tough to get access to private land unless you have lots of $$$. The BLM land that I checked out had very few Antelope, but the most populated area (Antelope) was at the far south end of the zone, around Bill, Wy. Very nice bucks walking around right in town! Try Montana, they have a Block Management program that pays the ranchers to let hunters hunt their property. Contact the Montana FWP for info. License applications are not due until June 1. Any questions, PM me.
