Saw some wolves this weekend at a sanctuary (http://www.wolfeducation.org/). It was interesting and eye opening. The impact they have on the ecosystem is amazing. There's a video out there of their impact in Yellowstone after they were reintroduced (quick search on YouTube will get you there). The sanctuary also has various foxes and coyotes.
Cool.
We used to visit the Louisville Zoo all day, then have a picnic at the car in the parking lot in the evening to listen to the wolves howling.
