That scene remind me of the late 70's back in Switzerland, we were sailing in that little lake, was beginning of spring (I was young and fanatical about windsurfing) the wind was freezing cold we had one of the old fashion 7 mm diving suit that we were sharing .... you know, the one in 2 parts with the pad on your crotch, had a hood, gloves and socks and we were breaking a thin crust of ice on the water surface, We had an old beaten up VW van bought from Swiss telecom for $ 500-00 and the beauty had a small petrol driven heater (independent of the engine) it was bliss to hide in there after a sail and drink hot tea fortified with 60% proof spirit! Had my trusty HyFly 111, ah memories!!!!
