After a week of three structure fires that claimed two lives in Door County, multiple fire departments were deployed to a reported cabin fire in the woods on Bay Shore Drive north of Little Harbor late Friday afternoon that turned out to be a unauthorized burn of an old cabin.  Sturgeon Bay Fire Department Lt. Brent Wiegand told Door County Daily News that when crews from Egg Harbor, Jacksonport, and Sturgeon Bay fire departments arrived about 4:30 p.m., the property owners were burning down the old cabin but did not have a permit.  He noted that they were issued a fine by law enforcement for illegal burning.  Wiegand emphasized that anyone looking to burn any clean wood or brush can ask for a free burning permit from their local municipality.
