History:
In 1975 a ceremony was held in downtown Lecompton on Elmore Street, celebrating the dedication of Constitution Hall as a National Historic Landmark. Until then, Lecompton's annual summer picnic, since before the turn of the Century, had been known as the Harvest Home Picnic. But because of the national recognition of Constitution Hall, Lecompton and Kansas Territory, the city fathers decided to call the summer outing Territorial Days.
