When actor Richard Herd returned home from a recent road trip to Colorado, his most prized souvenirs weren’t typical tourist trinkets.“I stopped at towns along the way for directions to the local junkyards,” said Herd from his West Coast home. “People would stare at me and ask ‘Aren’t you an actor? Weren’t you on Seinfeld?’”But 82-year-old Herd – who indeed appeared in several episodes of the popular ‘90s sitcom as ‘Mr. Wilhelm’ – wasn’t looking for recognition.
