Alright...here ya go kids ( I had some trouble with this cause there are so many cool places, historically, around here...plus I was up in Gettysburg for the wife most the day..sorry for the delay). It's the worlds last standing cast and wrought iron bridge and one of the worlds first.
ps. If anyone decides to go looking for the Little Rascals dog "petey" burial site...good luck. Found the cemetery, not the grave though..errr. I'll never go to a pet cemetery searching a famous animal again.
