DULUTH, MN (KDAL) - Even though the weather is more like winter, the downtown Duluth and waterfront merchants are featuring specials to welcome the arrival of spring.  They are calling it "Merch Madness" and the championship shopping runs from March 20th to the 23rd.  Sponsored by the Greater Downtown Council, the promotion is geared to help out the local family owned businesses you will find in the downtown and waterfront area of Duluth.  Get more information and maps of the skywalk system and parking ramps at downtownduluth.com
