Found it Steve.  Just got back from four days in Duluth, Minnesota.  My Wife had a convention there and we took our 345 and spent four days.  We stayed at Indian Point Campground which I liked a lot.  It is on the St. Louis River and just fifteen minutes from the Convention Center. 

I had been through Duluth before, but never stopped and spent any time there.  I loved the place!  We were treated to a Convention Picnic on Sunday night in a park next to the Convention Center and right on the Harbor.  Right next door was their excellent Aquarium and we had free passes to that as well.  On Monday night we had passes to go on a cruise that took us out onto Lake Superior, and then back into the Harbor where we spent an hour cruising by all the huge ships loading Iron Ore, Grain and many other bulk items. 

We both decided that if they hold the Convention there next year, we will go again and stay at Indian Point again as well.  The only draw back is they have only a few pull through sites with sewer.  They do however have lots of hiking trails and biking trails.  The campground is neat and clean and away from the noise of the city so its quiet at night. 

On tuesday night we sat at Grandma's Resturant (You know, Grandma's Marathon) and watched ships come and go through the High Lift Bridge into and out of Duluth Harbor. You can google it and see a lot of the pictures.  It was very scenic.
