Hey guys I just talked to a south dakota game and fish guy and he was very helpful. I'm trying to get a rifle tag for Mule deer next year. He was awesome at explaining the preference points and how I could purchase points this year and have 1 point next season. I'm just wanting to know the difference between west river deer and west river special buck. Should I purchase both points. Also what are some points I should purchase in order states such as wyoming and Colorado. I just dont want to miss out on a point that I would wish I had. Thanks for any help.
