23 does not have much pubblic land. Area 24 and 7 usually have left over licenses or 100% draw odds. There is state and National Grasslands in these two areas. Lots of Antelope as well. Here is a site that you can mess with and find all state lands as well. There are people in these areas that have tresspass fees if it comes down to that.
