An Afternoon Amongst Grizzly and Gray Wolves

Just got a new Nikon D5000. So I was anxious to use it. So I spent an afternoon just enjoying captured nature, at West Yellowstone's, "Grizzly & Wolf Discovery Center. Some may feel sorry for captured animals but these would have been put to sleep.. Actually the Grizzly were going to be killed for not staying away from humans. So instead of putting them down, they live like kings, in a wonderful enclosure.
There are two packs of wolves as well. I was there for their feeding. They shouted...
"Can we have two Volunteers?"
