Their is a Leif Erickson Park in Bay Ridge/Dyker Heights Brooklyn, created back in the day when that part of New York was home to the largest population of Norwegians outside of the midwest. Although most (though not all) of the Norwegian has moved on, there is still the crowning of Miss Norway every year in May.
I'd thought York County PA was the largest settlement of Scandinavian people outside of the Midwest in the 1800s, and in the 1600 and 1700s the LARGEST settlement of Scandinavian people outside of Scandinavia itself!
