My parents had a similar experience in their idyllic exurb, where affluent retirees can afford lengthy home renovation projects. A neighbor's multi-car garage had noticeable traffic to and fro, on a country road in a small town where everybody seems to know each other's vehicles. It turns out the contractor was dealing heroin from the garage. I think the scheme worked for as long as it did because, like your case, nobody suspected anything like that in such a location.
