certainly a lower tag fee would increase non-res tag sales and overall revenue, at $35 etc....every non-res elk/deer hunter would buy a tag just to have one just in case.
at $186/300+ you almost have to make it a special trip/hunt to justify that. ID requires a non-res hunting license, so essentially the same price as MT's tag I believe around $300 to hunt a wolf in ID/MT as a non-res.
