There's lots of other room for Grizzlies than just the zoo. I'll concede only that where they conflict with the dwellings of man, they should be hunted. But a grizzly-free back-country just so we can go play in the woods doesn't pass the test.
And spending tax money bringing grizzlys back to areas where they were eliminated is certain to get people killed merely to make some feel good. It's yet another example of the government endangering our citizens for no positive good.
