Capitol: Jefferson City
Getting down to the wire here, and the ideas are few and far between! Still struggling with ideas for Virginia, South Carolina, Michigan and New Hampshire. (Alaska and Hawaii are on "hold", while I finish the contiguous states and their display).
I had always planned on doing the Gateway Arch (construction started in 1963) for Missouri, but I needed something else too. Then I discovered that the first Olympic Games hosted in the United States were the 1904 Summer Olympics, held in St. Louis, Missouri. So I paired the Olympic rings with the Gateway Arch.
