Chattanooga, Tennessee, is nicknamed "The Scenic City" for its vistas of the Tennessee Valley from atop the many mountaintops that surround the city. Chattanooga and its suburbs form the second most populous metropolitan area in the valley. The Battle of Chattanooga was fought on nearby Lookout Mountain.
Decatur, Alabama, known as "The River City", dominated the economic landscape of north Alabama until the late 1950s, when the space race catapulted its neighbor Huntsville (see below) into that position. For most of the 20th century up to that point, Decatur held the top position in terms of economic impact and population. Its mixture of river transport and rail access has made it a busy hub of business, commerce, and manufacturing (chemicals and textiles especially) flowing down the river on the barges and boats of numerous companies and docking at the Port of Decatur.
The City of Decatur also claims the nickname "The Heart of the Valley" because of its location near the exact center of the length of the Tennessee River. Also because most north/south shipping traffic is funneled through the town utilizing three river crossings that are main routes for rail and road traffic between Birmingham, and Nashville. The city is also an important river port that uses intramodal facilities to switch shipping methods between trains, trucks, and barges.
Scottsboro, Alabama, "the Friendly City", is located on Highway 72, 40 miles east of Huntsville. It was founded in the mid 1850s and is most famous for the Scottsboro Boys and Unclaimed Baggage Center, as well as "First Monday," an open-air marketplace held in and around downtown on Mondays following the first weekend of a month.
