So I immediately start thinking ....... "A A"
What the heck does "A A" stand for? "Alcoholics Anonymous"? "American Airlines? "Associate in Arts"? "Alcoa Aluminum"?
Then it struck me - the owner of the car was of Norwegian descent ! That's the flag of Norway in reverse and not "A A".
I guess that's when you realize you've either been at this Morse Code thing too long; or maybe you just need that first cup of coffee of the day.
