I have been hunting Wyoming for about 15 years. Always DIY hunts. I have found the maps from the US Forest service to be very valuable. Also obtaining hunting maps for your gps with private and public boundaries in color will be helpful. Garmins Montana seems to have the largest screen for ease of viewing. The game wardens in Wyoming use them, and will show you your position in relation to the boundaries. Takes the guess work out of it. I hope is information helps.
