What do these events and people have in common? This date in history--March 6. Birthdays and birthday celebrations, mainly, but other historical events as well. My Dad always tells the story of how cold it was the day I was born--held the record for that day well up into the 1970s. The others are people I've met along the way who share this day with me.
