Grey Wolf, Yellowstone NP - We hit paydirt today - we were greatly blessed when a grey wolf passed by our vehicle, not 30 feet away! Several were reintroduced to Yellowstone in the 1980s and are typically very scarce. When observable, they are quite a distance away. To have one walk right by us, and so close, is a real treat! We watched him cross a small stream and then walk on by, completely ignoring us. Definitely a highlight of the day!
