The Yellow Pages have shrunk because business owners realize only some of those over 70 still use them, and no one else. Everyone else uses Interent search engines.
“... only some of those over 70 still use them...”
That’s me FRiend and there’s a lot like me around here. You are right of course and the white pages have shrunk too because of cell phones. With the Shuttle demise along with related businesses, it’s tough here on the Florida Space Coast but it will come back in time, it always has. Private enterprise is going to take over the space program.
