go elf themselves this holiday season. Enterprising “Chief Elf” Sophie, a 15-year-old from Cobble Hill, told The Post she is hosting the city’s first-ever ElfCon this weekend, an event she billed as a “kid-friendly hot cocoa crawl” — or a journey that’s just a little less jolly than NYC’s annual, boozy SantaCon.The 10th-grader, who chose not to reveal her last name for privacy reasons, hopes the event will attract families dressed as elves for a tour of the city’s finest winter dens when it kicks off at 10 a.m. Sunday in Union Square Park.
