Yep, i have to agree with you Tom on the rat catch . Interesting how our DNR doesnt study this aspect of furbearers. Granted no money but its like colleges , example Stevens PT, WI college of natural resources , they dont get money or grants they cant study and majority of studies are done by students and grad students with thier thesis. Now if it was deer or wolves, money would be found... One thing i know IF there werent many deer thus alot of people wouldnt buy deer lic, the DNR would go down the tubes... even with fishing lic.
