I think the boy in the permit department was handing you a line. If they didnt give you a set of rules, laws, or guidelines when you got the permit, then Id go down to the permit department and ask to see the "rules" in writing. Dont take anyone word for it. If they wont give it to you in writing, its BS.

Beware of associating with "Cheap" Squirrels. They tend to be very narrow minded, hypocritical, and will gag you if you question or disagree.
