Email from the North Slope:

I heard the polar bears were out at STP today so I went out there. Open this pic and you will notice it is in the exact place you went for your polar bear plunge. If you click on your mouse you will enlarge the pic and notice two white mounds on that little spit. The first one is the cub and the sow is at the end of it .. they are both sleeping. Thought you might get a kick out of that.
