I was at Hefner fishing for walleyes at about 11PM one January when I heard what seemed like some noisy drunks pull up behind my truck. I was afraid I was going to have trouble, but it turned out to be a crazy bunch of high schoolers on a video scavenger hunt. They were ecstatic to find a fisherman on such a cold night. After they videoed me and started to leave, one of the girls asked if I had any fish. When I told them I had two, they said that was major bonus points, and they were sure to win. Knock on wood, I've fished many times after dark, but never had a problem. I have known others, though, who have been robbed and assaulted.
