I actually had the MNR guy make me wade in from the middle of the credit up near wire baskets as I was crossing to the other side. Actually kind of scared me because the water was high and I was already feeling like crossing was a stupid decision...
I have seen people that have their licenses on the back of their hats. I would be a bit worried it might blow off. The CO's can also call in your licenses now, I hear about guys forgetting theirs and them calling it in all the time.
