On March 7, San Francisco Giants principal owner Charles B. Johnson penned an impassioned email to a select group of ultra-wealthy allies, signing off with, “Time is of the essence.”
He wasn’t scrambling to direct the Giants front office to sign a free agent, or rallying right-wingers to donate to a politician. He was drumming up support for his latest cause: Making sure a clam shack in Nantucket doesn’t open next to his $6.5 million cottage on Old North Wharf, which, according to public records, is one of at least four properties he owns on the Massachusetts island.
