LeSourdsville Lake Amusement Park was an amusement park located in Monroe, Ohio. Founded by Edgar Streifthau, the park originally opened in 1922 as a family picnic destination with swimming amenities. Throughout the 1940s, LeSourdsville Lake transformed into an amusement park with the addition of rides, attractions, and an arcade. The park was sold in 1961, and following heavy competition from nearby Kings Island, it was rebranded Americana Amusement Park in 1978. An electrical fire in 1990 caused over $5 million in damages and led to bankruptcy. The park continued to operate under several different owners before eventually closing in 1999. Americana briefly reopened in 2002 under the original name LeSourdsville Lake, but the effort by new owner Jerry Couch was short-lived as the park failed to turn a profit. Remaining rides and attractions were either sold or later demolished. In 2017, the city of Monroe received a portion of the land to build a city park and regional bicycle trail, and another portion was sold to a local vocational school seeking to build a new campus location.

West Middletown is an unincorporated community in eastern Madison Township, Butler County, Ohio, United States. It is located on the west shore of the Great Miami River about one mile from Middletown. It had about 200 people in 1905 and was formerly a station on the Cincinnati, Hamilton, and Dayton Railroad. Founded as Madison City, it received the name Heno when it was awarded a post office in 1882. Since there was already another Madison City in Ohio, the postmaster general demanded a name change. According to legend, as old-timers were discussing the new name around the cracker barrel in the general store, a can of Heno tea caught their attention. So the town was named for the tea. But in 1907, the postmaster general decreed the village was within the shadow of Middletown, and only a few postal workers had ever heard of Heno, making it difficult to sort and forward mail to the place. The government ordered the village to accept the name of West Middletown. In 1963 the postmaster general in another decree closed the West Middletown post office, transferring its business to Middletown.
