For one group of New Yorkers, the season's first snowfall was the signal to head to the beach in Brooklyn.
The legendary Coney Island Polar Bear Club saw in the icy cold Atlantic Ocean Sunday morning.
The club swims in the water every Sunday from November through April.
In addition to the exercise and cool thrills, they also raise money for the charity organization New York Cares and a camp for sick children.
While most New Yorkers would not even dare go near the ocean this time of year, veteran swimmers say it's a thrill unlike any other.
"I mean the first time I came down here I was apprehensive, nervous, scared, but once I went into that room over there in the [New York] Aquarium, it was amazing," said Polar Bear Club Vice President Tony Nastro. "There's an energy that comes from the people that do this, that just makes you feel you're in the right place, you're doing the right thing."
The club plans to ring in 2010 with a swim on New Year's Day.
