I was cleaning out old BackUp Drives and found this image of an early am Snow Geese Take-Off at the Blackwater National Wildlife Refuge near Cambridge, Maryland. This was taken 2 days after Christmas in 2007. It was early in the morning as I was setting up my camera & tripod, hoping for a mass Take-Off of the Snow Geese. I was using the 13 lb Sigma 300-800mm f/5.6 lens @ 300mm on a Canon 1D mkII. It takes a while to get this large zoom lens setup on the tripod with a Wimberly Gimbel head. And luckily I got setup before they had a mass take-off.
