Pittsburgh, PA
Opened 1952 as Greater Pittsburgh Airport, replacing the older Allegheny County Airport. The 1992 X-shape airside terminal (architect Tasso Katselas) influenced airport design nationwide. Was US Airways' largest hub through the 1990s — until the 2004 dehubbing collapsed traffic. The airport never fully recovered its hub status.
The Allegheny River (from the north) and the Monongahela River (from the south) meet at the western tip of downtown Pittsburgh to form the Ohio River, which then runs 981 miles to the Mississippi. Point State Park sits at the confluence — 36 acres of riverfront with a 150-foot fountain at the very tip, marking the site of the colonial-era Fort Pitt (1761) and the earlier French Fort Duquesne (1754) that was the casus belli for the French and Indian War. The Pittsburgh skyline rises directly behind the Point — the Steel City's downtown is wedged into the triangle of land between the rivers, a uniquely compact American downtown bordered on two sides by water. The Roberto Clemente Bridge (yellow), the Andy Warhol Bridge (yellow), and the Rachel Carson Bridge (yellow) — the Three Sisters — cross the Allegheny into the North Shore, where PNC Park and Acrisure Stadium sit on the riverbank.
Frank Lloyd Wright's 1935 house cantilevered directly over a waterfall on Bear Run, in the Laurel Highlands southeast of Pittsburgh. Built for the Kaufmann family of Pittsburgh department-store fame as a weekend retreat, Fallingwater is widely considered the finest American house of the 20th century — a horizontal stack of poured-concrete terraces that float over the stream rather than facing it. Smithsonian named it one of "28 places to visit before you die." The cantilevers were already sagging by the late 1990s; a 2002 structural restoration added post-tensioning cables to save the house from collapsing into its own waterfall.
In Canton, Ohio — birthplace of the NFL (the league was organized at a Hupmobile dealership in Canton in 1920). The Hall of Fame opened in 1963 and has been the football pilgrimage ever since. Bronze busts of every inductee, the Lombardi Trophy, the Twilight of the NFL Theater. Annual Hall of Fame Game (preseason) and induction ceremony in early August. The HOF Village complex around the museum continues to expand. KCAK is 5 minutes away.
Military Aviation Preservation Society — a hands-on warbird museum and restoration shop right at Akron-Canton Regional. The collection includes a Martin B-26 Marauder, a Douglas C-47 Skytrain, an F-101 Voodoo, F-105 Thunderchief, and dozens of others. Many aircraft are accessible for cockpit visits — kids and pilots alike love climbing in. The MAPS volunteers actively restore aircraft, so visits often include watching welders and mechanics at work. Less famous than the Air Force Museum but absolutely worth the stop on a Cleveland-area trip.
