Being in law enforcement, i'll reply to this. Check stations would not be a bad idea, but as stated previously they would be primarily for statistical purposes. I don't think anyone who took an animal illegally would be silly enough to check them at a check station on the off chance that it would get inspected closer than expected, but it may catch a few. I also agree it may be an issue as to who would be doing the checking. I would imagine there would be a funding problem, unless it's going to be volunteer, which kind of scares me.
Hopefully the DNR will be able to get back to full strength sometime in the near future, which would be the highest chance for further enforcement efforts. Also, don't forget to encourage your local Sheriff's dept to be as proactive as possible. They could be a huge asset, along with the eyes of all the law abiding hunters.
I've heard quite a few complaints about the DNR's license quotas, so check stations may offer an alternative to gain more accurate information about herd composition. I feel that anything that could improve herd quality would be a good thing.
