San Francisco

San Francisco

San Francisco is hills, fog, Mission burritos the size of forearms, and pastel Victorians stacked like dominoes. Karl the Fog has his own Instagram, the cable cars are still mechanically pulled by cables running under the street, and the Pacific shows up at the end of every west-bound avenue. The food is wildly good, the views are theatrical, and yes, you'll get cardio just walking to the corner store.

Pittsburgh

Pittsburgh has more bridges than Venice (446, and locals will tell you the exact number), three rivers crashing together downtown, and a sandwich tradition where the fries go inside. The mills are long gone but the neighborhoods they built (Polish Hill, Bloomfield, the Strip) still feed you like a great aunt. Carnegie Mellon and UPMC turned the old industrial bones into a robotics and medical research scene. The skyline reveal coming through the Fort Pitt Tunnel is the cheapest awe in America.
