Horse breeding
Worthington Valley Historic District is a national historic district in Reisterstown, Baltimore County, Maryland, United States. It is a largely rural district where the earliest standing structures date from the very end of the 18th century. Horse breeding and racing is a very large and lucrative business in the valley. Since 1922, Snow Hill and Worthington Farms have been the scene of the Maryland Hunt Cup Steeplechase. Located next to it is the Western Run–Belfast Road Historic District.
