If you’ve ever seen that program on life after humans, you will know that it doesn’t take long for nature to take over buildings and cover up that humans were even there.  This week we are visiting two ghost town of Pennsylvania. The first one is not far from Jim Thorpe in Carbon County and it’s history is a slight mystery.  And the second is located in Indiana County and has a much clearer picture of life there.  But can we prune away the weeds and uncover more history?
