It can get cold and dry out there on the ice when the fish aren't biting. Count on some innovative Wisconsinite to come up with an idea to correct that.Aviation officials have grounded a drone beer delivery service for thirsty fishermen on the frozen lakes of Minnesota and Wisconsin.  Lakemaid Beer, which calls itself the fishermen's lager, had hoped the delivery service would take off in beer and bait shops. The idea was for customers to ring shops giving their GPS co-ordinates allowing the six propeller drone to carry the beer across the frozen lake. However, the Federal Aviation Administration has yet to approve the use of drones for commercial use and stepped in to shoot down the idea.
