New York City is bracing for a very busy 4th of July weekend as World Cup matches mix with huge Independence Day celebrations for America's 250th anniversary and apparently popstar Taylor Swift's wedding to football player Travis Kelce at Madison Square Garden. Information has been leaking out, with reports of a rehearsal dinner followed by a larger celebration in front of 1,000 people. The big event also coincides with a massive heatwave that has prompted city officials to declare a heat emergency.
