Love at first sight. My first weekend here was full of delicious food, urban exploring at abandoned steel mills and bike riding galore over many, many bridges. I've since been back at least 7-10 times from that first trip to Pittsburgh about five years ago. Love the Andy Warhol museum, Meat & Potatoes, the endless bridges and hills, bike riding and the plethora of tasty foods. Too many to name. I also met my wife on a trip to Pittsburgh ;).
Pittsburgh is the perfect weekend getaway city if you live in Buffalo. A pretty reasonable drive and lots to do. I adore the city and am looking for another excuse to go ASAP. Ever since I've received my pilot's license, it's one of my favorite places to fly to as well -- a short 75minute flight and passing over the Allegheny River and endless mountains and a wonderful, friendly airport make it a perfect flying destination (go to Voyager at KAGC).
