Hi Blondie,
I read a lot of scifi and was I surprised to be reading a story about life after a globe encompassing war where humans were punched back to the to just before the Industrial Revolution. The main character was traveling from area to area and encountered a group just like this story and barely escaped with this life.
Was that story "The Postman" by David Brin if I remember right?
I think that story was made into a movie, which I have not seen.
