Back on a Saturday night in 1969, which happened to be St. Valentine's Day that year, in a 4-person Computer Sciences (first CS Dept. in the nation!) grad student office on the 4th floor of the Math Science building of Purdue, Hal Hart & Ruth Mazur announced their engagement to 12 of their closest friends in grad school plus Ruth’s sister Peggy visiting from Ohio State. This was celebrated by ordering pizza. The event became known as St. Hart's Day, and was commemorated for years thereafter on the Saturday night closest to Feb. 14. It was made special by serving heart-shaped pizzas and the occasional tradition of young couples announcing other engagements at the party or meeting at the party and then dating or getting married. 
That tradition has died out, but 42 years later (2011) Ruth & Hal were introduced to geocaching by Crash77 who was a guest lecturer for a learning-in-retirement group (Omnilore) hike on the Bark Trail in Hermosa. Their active retirement lifestyle got busier than ever, what with caching on all our travels, a 214-day consecutive streak triggered by AdultDaughter1 (Erika) who lives in Rhode Island, planning the St. Hart’s ‘Hood series of caches
(deployed in 2012 along the boundary trail separating our Torrance Hollywood Riviera neighborhood from PVE + 1 in RI originally and now 3 in RI!), and over 30 states in which we've cached and just under 30 foreign countries. In 2012 Xman (imanxman) introduced us to Meet-and-Greet events where we have enjoyed putting faces to familiar geocaching monikers. In 2013, we re-incarnated the St. Hart’s Day celebration as our first geocaching meet-and-greet event and hosted fellow SoCal geocachers. We called it St. Hart’s Meet-&-Greet #45
(even though that’s not literally correct). 
Thus, on Saturday, February 17, we will again celebrate St. Hart’s Day as a geocaching meet-and-greet event and you're all invited. We’ll increment the number and call it St. Hart’s Meet-&-Greet #50. We’ll serve pizzas from a favorite local pizzeria and a typical variety of drinks. GZ is our house. 
Parking is only on the opposite side of the street and there’s generally lots of spaces within a block or around the corner on Via El Chico or Calle Mayor within about 100 yards.
Pizza deliveries will be scheduled for about 5:15 pm and 7 pm, so come early in the evening or later, whenever you’re you’re available. We will welcome and entertain guests until there aren’t any more (we’re night people), and will spring for a third pizza delivery if necessary.
We’ve now met dozens of local geocachers and hope to add to that number on Feb. 17. This is also everyone else’s chance to put faces and real names with geocaching monikers. Meet new friends. Trade geocaching stories. Trade and discover trackables. Divulge spoilers. Plan that next cache run together...
Please help pass the word to your other geocaching friends because not everyone knows how to turn on event notifications. (If you have a favorite Muggle or two, you’re welcome to bring them too.)
Weather Forecast for Feb. 17 in Redondo Beach: Sunny, Temperature about 60, give or take, with low probability of rain! (Look for posted signs directing you down the left side of our garage to the pool deck in back, or inside if weather turns — ocean and sunset views should be available from either location)
