Keith's Visiting Thief on Lake of the Woods

Keith has an unexpected visitor, while ice fishing on Lake of the Woods, who tries to steal his fish.
Info From Licensor: "I was Ice Fishing on Lake Of The Woods in Mn. I noticed Minks out playing on the ice and tried to video that - nothing but black dots in the distance. When I reentered my Ice Fishing shack - I could hear something scratching to get in. It came through the back of the shack where I had some snow piled up. Since I had my IPhone out already, I simply started to record. I though he would turn around when he saw/heard me, but he came in and started to look around.

As a side note, after he left the shack - I went to show my buddy the video - when I returned there was a walleye missing - he must have come back for seconds."
