It's pretty easy to get permission to trap beaver at this time of year with them taking all the trees down.....lol! Go for a drive and look for beaver damage and knock on the landowner's door. I just did this two days ago and not only did I get permission to take some beaver and to snare for coyotes, but the landowner said that he might know a few people that may be interested in getting me to trap their land as well. Around here word spreads fast that there is a trapper in the area willing to trap for FREE.
The fella with the beaver problem initially thought about what it would cost him and when I told him FREE, it was an easy sell.
