1805Shippingport Island
Shippingport Island, a peninsula near the falls of the Ohio River, held horse racing. The track was called Elm Tree garden. During this time, the Falls of the Ohio was primarily occupied by French settlers, whose fur-trading businesses carried them upriver from New Orleans. Racing in Louisville was becoming popular and it was felt that its location other than city streets would be safer.
