In Iowa or Nebraska, a person doesn't have to wear blaze orange while bowhunting. You were bowhunting right? Now firearm hunting...thats differant. Gotta wear it while your hunting with a firearm. Either way, I'd welcome him and cooperate. Then I question him like Elliott Ness. These guys usually have a huge amount of information on where the big ones are, what kind of year it is, ect. ect.
