For the 31st annual Polar Bear Jump-Off, about 100 people leaped into the cold water of Resurrection Bay on Saturday.
"Once you get down there, your nerves kind of just stop and you're ready to go," said Christie Hill, jumping for an 18th year.

The fundraiser benefits the American Cancer Society.
"People that go through cancer are going through a lot worse than we are, so I think that that's the best way to do it, so might as well just keep jumping and helping them out," Hill said.
