I don't know the numbers, I've been in Idaho over here at school. The guy I know that hunted archery is the one that estimated 75% of the employees hunting up there harvested. And I'm sure he is just basing that off the people saw while hunting up there and talking to people.
And I really doubt that the security guy saw every vehicle in there. . .
EDIT: And I'm talking about Weyco's security guy. . . The tubby guy that looks like a mall cop.
