RE: Thunder Basin Nat'l Grasslands
Most of the TBNG is in area 27. The odds of drawing a non res tag for that area is about 12%. There are alot of areas around there that are 100% draws, but they are mostly private land areas. You can call the Game and Fish Dept. and they will send you a list of landowners that will let you hunt their property. Most charge some sort of tresspass fee.
