NC did the same thing last year. The bear biologist wants to know who is actually targeting bear, what the incidental harvest is (were you actually hunting for bear), and what the harvest rate is now that we legalized baiting (with restrictions depending on what part of the state your are hunting in). The tag is only 10 bucks though and free if you have a lifetime license and ask for the tag.
$20.00 is not bad but I would want to know why and where is the money going.
