It's been over 50 years since I bought my first car ... a Dodge of course ! And I can recite EXACTLY, without hesitation, the entire VIN of that car ! Now, I don't even know the license plate numbers of my current cars today. What is it that makes an indelible mark on your mind ? Anybody have "total recall" on something, or someone, or some event, that you would ordinarily think would be long forgotten ?
