It looks like they operate in units 26 and 29. 26 can be drawn with 2 points, with roughly 40% chance with 1 point. 29 looks much more difficult to draw depending on if you are trying to get a Type 1 or Type 2 license. Type 1 you're guaranteed the tag with 6 points and have a 33% chance with 5. Type 2 you can draw with 1 point and have a 50% chance with no points. Type 2 would only be valid on private land, which it says they operate on a large cattle ranch, so you could have a decent chance at drawing your first time.
