Born a port town where the St. Louis River drains into Lake Superior, Duluth is still a very industrial city with some interesting sites to visit. We start our walk around along the harbor to check out the lift bridge over the Duluth Canal.  It is a cool kind of draw bridge.  A 386 foot section of highway is suspended below an impressive steel superstructure that juts high above the channel.  Huge counter weights, 500 tons a piece, do most of the heavy lifting when the operator sets the bridge in motion.  It can provide as much as 180 feet vertical clearance for passing boats.  We witness a couple short lifts for fishing and tour boats but timing wasn’t quite right to see the full stroke up close when big freighters pass through.  Before this was a lift bridge, it was an aerial tram that moved a gondola loaded with people and cars across the channel.  That would have been fun to see…and ride.  Nearby we spend some time in the Corp of Engineers Maritime Museum checking out wreck history on the lake and other stories from these great bodies of water.  We wander on to check out Duluth Pack and of course Duluth Trading Company which is packed with much of the same merchandise and silly messaging as seen on their webpage. We stroll a bit more lakefront in route to Old Chicago Pizza for lunch.
