Pittsburgh has one of the most remarkable entrances out of any city. Most cities you can see from miles away, with skyscrapers alluding to it's presence before you can hear the bustle of activity. Pittsburgh has tall buildings, but the are nestled onto the point created when the Monongahala and the Allegheny rivers merge into the mighty Ohio river. Driving in from the airport, no hint of a city is given, until the last moment. Emerging from the Fort Pitt tunnel, you burst from the center of a hill to see the city surround you, before diving down the bridge into the heart of downtown.
