I was referring to the Great Lakes population.  I am not sure we disagree
that much.  My point is just that, absent some particular reason to believe
an individual was a released pet, in my opinion they are more likely than
not to be dispersed from the established populations.  Obviously, in your
area, many are known to be released.  Around here, there aren't that many.
