The OP said it was a county park. Around here the county park rangers are not armed. It is also almost inconceivable that a county park would be one of the protected wildlife areas that has been mentioned. Also, I am not 1005 certain, but I think "Glacier Girl" is not a female, but that his screen name refers to the famous P-38 of the same name that was excavated from under the ice on Greenland.

No real bearing on the situation, but sort of interesting.
