Every day is now DynaMets Dash Day in the Citi Field parking lot, where kids and adults can run the Shea bases and even stand at the Pitcher’s Plate, as the plaque and rules insist the pitching rubber is officially called. You might deduce from the hint of a crowd gathered around this marker that Mets fans are particularly intrigued by where third base sat. It is said a ninth-inning Mets rally is actually buried underneath the asphalt, where it expired ninety feet from home. But I think that’s just an urban myth.
