My guess would be that CO's would be the most likely to monitor group activity on the lake, but have not heard of any fines in our area. I had a CO stop by the perm shack the other day (I was there alone), I asked him in, but he said they are not allowed to enter a shack now because of Covid restrictions, he did not ask to see a license, but since he knew me I was not surprised, later I have heard that they are not asking to see anybody's license right now. My area is not very populated, maybe down east they may be watching a little closer.
