I’ll bet they are gathering there because the fast food places are serving lutefisk.
An old coot from the north woods calls the county extension agent one day to report that a family of skunks have taken up residence under his high stick house and he wanted to know how to get rid of them.
Agent expains the options for live traps but says that he heard they are repelled by the smell of lutefisk, so he might try thorowing those under the house on a regular basis. The old coot thanks the agent and says he'll try it.
A few weeks later, the agent gets a call from the same old coot who reports the lutefisk worked great and drove the skunks off. But now he had another problem.
The agent asks what that was. The old coot replies "Now, I have a family of Norskies living under the house."
