I went to the Allegheny National Forest in search of photo opportunities. Well, I never found the access to attempt to find the water falls I wanted to today. I traveled to the Kinzua Viaduct. Started in 1881 and supposedly it took only 94 days to build! The viaduct suffered being hit by a F-1 tornado here is a link to the story.

The following video Builders of Bridges (1928) Handling Hot
Rivets “not by me I take no credit for the video” (Johnny from Texas posted it). It shows the same technique
that the Kinzua Viaduct was constructed.
Enjoy the photos folks! Tomorrow I am chasing steelhead around Erie somewhere.
