"Creston was a tiny train stop on the Milwaukee Railroad. The owners of the Creston General Store thought that a "life-size" dinosaur might entice rail and highway travelers to their establishment. The sauropod was designed and built by Creston resident and handyman Old Ike Murphy. Composed of concrete over an armature of wood and scrap metal, including railroad ties, the dinosaur measures an impressive 60 feet long and 20 feet tall." https://www.atlasobscura.com/places/creston-dinosaur
