As a truck owner, I always drive with my tailgate up. However, I've known people who would drive with it down claiming it gave them better gas mileage. I'm not sure if that's true, but I now know that it's against the law.
It's no secret that it's been warm lately. While heat and humidity are signature components of summertime in the Northland, this spring/summer's heat has been historical for the Duluth area in two different ways.
