There is a chance you may be charged, Just due to the fact that some of WI's wardens are idiots. But you are acting legally So I would not worry about it too much.
There are very good reasons to be armed in the forests of WI.
The DNR is an odd bunch, I would wager that an ignorant DNR warden will charge you wrongfully. I state this from my dealings and witnessing other peoples dealings with a select few wardens up this way.
One DNR clown was ticketing snowmobilers for having an "Afternarket Exhaust System" on their snowmobile. Yet there is no lawagainst having a non-stock exhaust, Only that noise levels cannot be exceeded.
Some of the people that got ticketedhad the factory equipped exhaust system on their sled, but took the time to have it ceramic coated, or polished. So it did not look like astock cheap exhaust system. But got ticketed anyways. Those that went to court won their cases. Others found it to be less expensive by just paying the fine instead of driving back up here, and staying at a hotel to make the court date.
Just be prepared to have a court date to clear your name if you are wrongfully ticketed.
