1) Some “big-league” cities trumpet the fact that they’ve got a big-league amusement park. The Pittsburgh area can claim two: Kennywood Park, close to the city, and Idlewild, a bit farther out. Both are open for business—wait, make that pleasure—this summer. Check park websites for special attractions and updated health/safety info. Kennywood dates from 1898. It’s known for a world-class collection of mechanized rides, including three classic wooden roller coasters plus the steel-framed Phantom’s Revenge and Steel Curtain. There’s a nice assortment of kiddie rides, too. Kennywood is open daily until August 22 when a more limited schedule resumes. The park maintains a constantly updated list of attractions open and closed. 4800 Kennywood Blvd., West Mifflin. (M.V./R.H.)
