Yes, it is true! President George Washington traveled to Charleston for a visit during his second term (one of our original tourists?). In May of 1791 Washington spent a week in town, and made quite an impression on the citizens of Charleston. They held a big party for him, because galas and festive events are a tradition here.
Years later, a park was dedicated to Washington in the heart of the city, and a statue erected in honor of our first president.
