Each year on the second weekend of October Mound City's population swells from about 1000 people to 10,000, thanks to the work of Danny Smith of Pleasanton. As president of the Linn County Historical Society, he had the idea to of having an art show on the courthouse lawn, when our sugar maples were in full color. He felt it would call attention to the graceful architecture of the lovely old building. Due to rain that day it was moved to the Linn County Fairgrounds.
