About the only big chunk of public land that is easlily and legally accessible in 23 is up in the northwest corner just off the Powder River western boundary for the unit. That BLM also ties in with a decent size WIHA private piece of property along Beaver Creek that you can look up on the G&F website. You don't need to ask for permission to hunt it, but you have to access it from the north, as the road to it from the south is private and they issue tickets there quite often for being on it. There are pronghorn up in that area, but it's a tough hunt through country that doesn't look like typical pronghorn country. It's an area requiring that you park and do a lot of walking with binos and spotting scope to find them. I have no idea who the previous post is referring to about calling for a map, but the best thing to do is order them through the BLM (see below) . The other thing to do is to contact officials out there and get a map that shows all the roads the county maintains that the public is legally able to be on because that's a big problem out there. Just looking at a regular BLM map would make one think there is all kinds of land to hunt in a lot of the units, but a big percentage of it is landlocked by private property with no way to legally get into it. I'd also strongly suggest that you guys have a GPS with a landownership chip in it for actual use on the ground when you're out hunting to avoid a trespass ticket. Those tickets are at least $200 the last I heard and both the Sheriff deputies and the G&F Wardens will be out and issue one in a heartbeat if you're on private land without written permission. Other than the signage on the perimeter fences of that WIHA, there is no way without that chip in a GPS to know that you are on public land since fences are meaningless out there. Below is the BLM link for your maps. You will want to order the Buffalo, Gillette, Kaycee and Reno Junction maps in order to cover all of unit 23 or the first two to do the hunt up in the part of the unit I mentioned earlier. The BLM phone number out there to call and order them is 307-775-6256. Good luck!
