This topic comes up every year and this is the third year here.

Some people have issues that come up and keep them from hunting. In the past I have known or heard about divorce, loss of job, broken vehicle, could only hunt a day or two, sickness, emergency, etc.
The other side is those who falsely report or don't report. I think most are falsely reporting in the way as if they hunted but were unsuccessful then they just say they didn't hunt so they don't have to answer the next couple questions. I think this is the F&W's fault. You can make a reporting system that forces peole to give answers. Don't give them the easy way out.
I really doubt that anyone applies for a permit thinking that if drawn they won't hunt.
