Dayton, the Gem City (no one is really sure where the nickname came from, so just accept it), is a moderately sized city in southwest Ohio. About an hour's drive north of downtown Cincinnati, the city is most famous as the home of the Wright Brothers, hence the location of the founding of modern flight.
Beyond the Wright's, Dayton is known as a city of innovation with such famous inventors as John Patterson (founder of NCR) and Charles Kettering establishing businesses in the late 1800's and early 1900's.
Today Dayton is experiencing more difficult times. Even so, the people of Dayton continue to showcase that innovative spirit and a surprisingly vibrant cultural life in the town. It may not make the main tourist lists, but that suits many just fine.
