We went for 2 days to photograph at the Blackwater National Wildlife Refuge in Cambridge, Maryland. Early in the morning, along the Wildlife Drive on the second day we saw a huge flock of Snow Geese flying out under a heavy cloud cover. They were quite high and took a few minutes for the waves of them to pass by. Probably 500 to 700 (or more) passed by in multiple waves.
