Wondering if a non-resident would include a Canadian or is it referring to residents of other states in the U.S. only?
Would also like to know details on if I could purchase and use a turkey tag?
Anyone can buy tickets for Idaho's Super Hunts. Most of the people who enter are from the US, but every year a handful of entries come from another country. A hunter from Australia won a moose tag in the 2009 Super Hunt drawing. Also, since you don't need an Idaho hunting license to enter the Super Hunt drawing, you can purchase entries for friends and family, too.
If you are asking if a Canadian, like yourself, can purchase a turkey a turkey tag, the answer is yes. You would be considered a nonresident and would need both an Idaho nonresident hunting license and a turkey tag. Idaho has both controlled hunt tags and general season tags for turkey hunts.
