<P0-S0> Huntington is a city in Cabell County and Wayne County in the U.S. state of West Virginia. <P0-S1>  It is the county seat of Cabell County, and largest city in the Huntington-Ashland, WV-KY-OH Metropolitan Statistical Area, sometimes referred to as the Tri-State Area. <P0-S2>  A historic and bustling city of commerce and heavy industry, Huntington has long-flourished due to its ideal location on the Ohio River at the mouth of the Guyandotte River. <P0-S3>  It is home to the Port of Huntington Tri-state, the busiest inland port in the United States. <P0-S4>  Surrounded by extensive natural resources, the industrial sector is based in coal, oil, chemicals and steel all of which support Huntington's diversified economy. <P0-S5>  The city is a vital rail-to-river transfer point for the marine transportation industry. <P0-S6>  Also, it is considered a scenic locale in the western foothills of the Appalachian Mountains. <P0-S7>  This location was selected by Collis Potter Huntington as ideal for the western terminus of the Chesapeake and Ohio Railway, the predecessor of what would become CSX Transportation which still operates CSX Transportation-Huntington Division in the city to date. <P0-S8>  The railroad founded Huntington as one of the nation's first planned communities to facilitate the railroad and other transportation related industries at the railways western terminus. <P0-S9>  Developing fast after the railroad's completion in 1871, the site was previously a collection of agricultural homesteads, and is eponymously named for the railroad company's founder Collis Potter Huntington. <P0-S10>  The first identifiable permanent settlement, Holderby's Landing, was founded in 1775 in the Colony of Virginia although the site had been sparsely settled by the French as early as 1609. <P0-S11>  With the exception of the neighborhoods of Westmoreland and Spring Valley, most of the city is in Cabell County. <SEP> <P1-S0>  The Appalachian Regional Commission defines the region as consisting of thirty-two counties. <P1-S1>  This region roughly overlaps with the Appalachian mixed-mesophytic forests, which begin in southeast Ohio and southwest Pennsylvania and continue to north Georgia and Alabama. <P1-S2>  The mixed-mesophytic forest is found only in Central and Southern Appalachia and eastern/central China. <P1-S3> Appalachian Ohio is a bioregion and political unit in the southeastern part of the U.S. state of Ohio, characterized by the western foothills of the Appalachian Mountains and Appalachian Plateau. <P1-S4>  It is one of the most biodiverse temperate forests in the world. <SEP> <P2-S0> The pepperoni roll is a snack popular in West Virginia and some nearby regions of the Appalachian Mountains such as Western Pennsylvania, Western Maryland, and Appalachian Ohio. <P2-S1>  It is ubiquitous in West Virginia, particularly in convenience stores, and is arguably the food most closely associated with the state. <SEP> <P3-S0> Country Club Bakery, located in Fairmont, West Virginia, USA, is a small family owned bakery that is significant because it is the home of the pepperoni roll. <P3-S1>  The bakery is located on Country Club Road, but the original bakery (where the pepperoni roll was invented) was located on Robinson Street. <P3-S2>  The pepperoni roll is a snack popular in West Virginia and some nearby regions of the Appalachian Mountains. <P3-S3>  Ubiquitous in West Virginia (particularly in convenience stores), but typically little known elsewhere, it is arguably the food most closely associated with the state (a competitor for this distinction is the ramp). <P3-S4>  The first pepperoni rolls were created at the Country Club Bakery in Fairmont, West Virginia by Giuseppe "Joseph" Argiro at the Country Club Bakery in Fairmont in 1927, some argue that it was not invented until the 1940s, but no one disputes that they originated at the Country Club Bakery. <P3-S5>  Fairmont, West Virginia, claims the title of "Pepperoni Roll Capital of the World."
