The eyes of the golf world are on Long Island this week as the U.S. Open gets underway at the Shinnecock Hills Golf Club in Southampton.
Security will be tight as up to 30,000 people per day descend on Southampton, but local officials say they are ready.
Hundreds of police officers from across the Island have been drafted to protect the event. Fans will be screened for weapons and explosives. Large bags are prohibited, and many items such as selfie sticks and tablets are banned.
In addition, there is a ban on private drones for the duration of the tournament.
