Wy is a beautiful state but run by ranchers and energy companies.
Be very careful in WY DIY hunts around private land. If you even pull into a ranch road to do a three point turn around to reverse direction during hunting season you can be sighted for "trespass while hunting" and fined nearly $300. When your word against ranchers you loose.
If you are near private land use a GPS with tracking around private land as the fences do not always follow public land boundaries and again you may need to prove you did not stray onto private land. Also you can not inter private land w/o permission to retrieve game, again no fences or signs to say it is private.
Some ranchers are great people but many look at the public lands and animals on them as theirs. I have seen cowboys on horseback whooping it up down draws to run deer onto there land so as to charge hunters $1500 each for a trespass fee to take a mule deer off there property.
