Thanks for sharing the TR and pictures Chicago. Alaska has such stunning scenery. I have to ask though, are those really polar bears or are you pulling our chain? The "bears" are so small and fuzzy in the picture, I'm trying to decide whether they're real or you took a picture of some goats and messing with us. :-) If you weren't kidding...AWESOME.
These are mountain goats. Dall sheep are very similar and also always in the area. This was mostly a joke for my friends in the Lower 48 who kid me about living in igloos, fighting off polar bears, and having lunch with Sarah Palin all the time.
Since I made the joke I had to research a little to confirm my assumption that there was NO WAY polar bears would be way up on a mountain or separated very far from ice and the sea.
