Bonus: Trails Together

The Three Rivers Heritage Trail in Allegheny County extends more than 33 miles on both banks of the Allegheny, Monongahela, and Ohio Rivers. The robust trail network has been decades in the making and would not have been possible without an equally robust network of people committed to trail work — including, perhaps most of all, Allegheny County's "trail czar," Darla Cravotta.
