Last weekend was the Duluth CouchSurfing invasion. CouchSurfing is a great way to connect with other travelers in your city and around the world. About thirty-five of us made it all the way up to Duluth, Minnesota for a chilly February weekend. Madison has had such a mild winter, it was a bit shocking to take on the North Shore's 15-degree weather. Still, it was a great getaway, even if for only a few days.
