I believe it, there was an article several years ago in the Anchorage News. It was based upon a tagged bear that had a radio tracker attached to it. It was a garbage bear, so instead of killing it like they normally do with Black Bears up there into garbage, they put that tracking device on it. Well they dropped it off on the lower Kenai Pennisula which is up to five hours by car and two hours like a crow flys. Anyhow they tracked it every twenty minutes, it made it's way back to Eagle River, even swan across Cook Inlet. Dots were laid out on a map to show the bears progress, it was simply cool how far that bear had traveled and it's sense of direction straight back to his garbage cans. Of course he ate a bullet later that week, but shows how amazingly determined these creatures are...
