Set between the Monongahela and Allegheny Rivers and a mountain ridge called Mt Washington, Pittsburgh has a unique character that is evident from the moment you arrive. Juxtaposed with the rumbling freight trains and the iconic bridges are the Bladerunner-esque self-driving Uber vehicles, scanning the roads with spinning Lidar scanners. Experiencing periods of boom and bust since its founding, the city is in a boom now (real estate that used to sell for $30,000 now goes for $300,000), and it's a fun place to visit, with top-notch museums, great gardens and parks, and amazing food, from humble to haute. Indeed, the once-struggling city has rediscovered itself as a food and brew mecca.
Carnegie is the biggest name in Pittsburgh – Scottish-born Andrew modernized steel production, and his legacy is still synonymous with the city and its many cultural and educational institutions. Second-biggest: Heinz, of ketchup fame, a company established here in 1869.
