What IS It About March 28?

Hats off to those who were born on March 28.  I have accumulated a large collection of these wonderful people in my life, far more than any other birthday on the calendar.  My father-in-law, our best man, another very dear friend of ours -- Chris -- from the volleyball era, one of Son #3's godparents, my friends Amy and Marlene from high school, a former co worker, and at least one current co worker.  There may be more in my extended circle of acquaintances, whose birthdays are not yet on my calendar.  People who are experts in astrology may be able to offer opinions as to why this is (and why a Libran would surround herself with so many Aries personalities!).
