After a ridiculously warm weekend, it seems like spring has arrived early. Before you know it, thousands of Minneapolis-types like myself will be driving up Interstate 35 to the cool shores of Gitche Gumee.

Since its post-industrial low point a few decades ago, Duluth has built Canal Park into one of the top-drawing tourist spots in the state. It’s definitely a great place, but I continue to be amazed by how much prime Canal Park real estate is occupied by pavement for storing cars. After a visit last fall, I made this map and found there are 21 acres of surface parking in Canal Park.
