It was a cold day. I had been watching this guy for a while. I got out of my car and sat down on a concrete boat ramp. The lake was frozen except for a small area where an airater was running which kept the ice from forming. He did not seem to mind me being there. I was watching his every move through the lens. He was walking around the edge of the ice, when all of a sudden he took off in a run to dive into the water after a fish! All I did was snap the shutter. This was so exciting! It was 20 degrees that day, but I did not feel cold, just excited! I am using an Olympus E3 camera with a 70-300mm lens 750/sec f5.6
