sorry, i didnt answer all your questions...
where we hunt antelope south of Gillette (area 24) it is like 100% draw area for both resident and non-resident.Most areas are open to most types of hunting. We didn't fill all our tags with our bows, so we'll get them with guns.

The BLM (Bureau of Land Management) have maps available for those areas. I'm not sure if it's the maps you were talking about, but they identify all state, federal, and private land (although not who actually own the private land). You can contact the BLM office in Buffalo, Wyoming at (307) 684-1100. That is the closest office. They should be able to send you the maps. I think they cost like $3 each. Or, you can order a Gazatteer online for Wyoming. The one we use is DeLORME. Go to their website. I do technical mapping for work and we use both of these types of maps.They work well for hunting also.

Although, one secret is to just go drive up to landowners and ask if you can hunt. It takes a lot of guts, but the worst they can say is NO. We do a lot of that for mulies, antelope, elk, and coonhunting.
