Never been over the bridge
I lived on the Cape from 1976 to 1988 and met people frequently that had never been to Massachusetts. They had never been over either bridge. I was shocked. I assume now those folks would be rarity. So are there any reddit people or people you've met that have ever left the Cape.
There was a story that circulated around Brewster long ago when the population was under 600 about a gentleman that took the train to Boston and was stunned it had a roof over the whole city...he never left south station
