PIW stands for Partnership in Wildlife. I think it is for residents only. It cost you $10.00 and there are a limited number of tags. For example, there were 3 PIW/deer tags this draw not sure how many for sheep, antelope, elk, etc. You get to hunt any open zone any season you want. So, basically you can hunt the whole state during archery, Muzz and Rifle with the respected weapon of the season. The money they collect goes in a trust for wildlife projects. It is a slim chance to draw, but I don't mind giving $50 or $60 bucks additional for wildlife.....
