Couple more things . . .
If you are stuck on hunting around Gillette (NE Wyoming), go to the G&F site and go to "Public Access" link. There is a lot of private land that is available in Wyoming called "Walk-In areas" and "Hunter Management Areas". They are listed by county. The Walk-Ins are just that, the HMA's require written permission which you can apply for and recieve right off the web site.
As far as maps, I like the book by DeLorme called "Wyoming Gazeteer and Atlas". It is an atlas showing the entire state. Shows land ownership and highways and such. Blue: state, orange: BLM, green: Nat'l Forrest, etc. DeLorme makes them for a lot of states.
