Grew up in nearby Monongahela, so I always knew about the park. Whe we started riding in the early 90's we started travelling there from Pittsburgh to ride. Always a fun place. Just remember those trails were built by local equestrians, and they have always kept an open attitude for bikes. Love the roller coaster type, in-and-out, up-and-down feel of Mingo. Would like to come back with a bike someday and go back out there.
