I was invited to watch the 4th of July fireworks atop the Kurth tower before the current owners bought the property. Every one of the 12 frames has dozens of fireworks–just look closely. The main display is from the Stone Arch Bridge, of course.
Summertime is when Duluth goes to the lakeside to listen to music, visit traveling fairs, and talk to neighbors about the smell of the lake. As seen from the castle walls.
