A great deal of pronghorn hunting success is having access to land. I assume that you do not have any preference points so that puts you is a little bit of a spot. Units that can be drawn easily with no points are usually substantially private land, and the public land available in these units gets very crowded. Most of the good private land either is being used by the owners who guide hunts or has been leased by outfitters. The units with access to good public land are hard to draw unless you have accumulated preference points.
Even if you go for the Special draw ( higher priced) it is hard to get into an uncrowded unit with zero preference points. If you want to join the crowds it is still possible to draw licenses in easy-draw units and be successful but it surely will not be like the TV hunts where there is unspooked game and no other orange hats in sight.
If your father wants to use a guide to give you access to private land I would suggest that you smile and thank him.
