Whatcha lookin' at

I went up to northern MN on a little day trip with my brother and stopped in Ely and visited the international wolf center. They had two wolves able for viewing when we got there. Their names were Aidan and Denali. When we first got their, the two brothers were off sleeping and we were not able to get really and good pictures. so after spending some time checking the place out the two go up and started walking around. Denali here walked right up to the glass and started checking out us on the other side. It appears in the picture that he is growling or snarling at us, but i assure you he was not. He was still tired and this picture was taken right after he was finished yawning.
