My good buddy Larry runs a Plastics business, and makes custom work for his customers. Now Larry has never hunted a day in his life, he is a city boy. Well he thought he had a good idea for a hunting blind.
A customer had him make some Mylar panels to place around her back yard to give it an appearance of being much larger. Larry saw that it reflected the scene around it making it blend in with it's surroundings. He sent me the idea, put these panels up and sit inside. Animals would not be able to see you and the blind would be invisiable. Yea right! First Bull Moose, or Grizzly Bear that walked in front of it and saw it's own reflection would think it had a new invader in it's territory. Good way to get killed when they charge the blind. I learned that lesson when a friend in Eagle River tapped on his window and a Bull Moose charged his living room window when it saw it reflection. Distroyed the living room.
Hated to bust Larry's bubble, but did not want him to get sued either when one of his customers got hurt or killed.
