The NCAA basketball tournament kicked off Thursday, and many Brooklyn residents got swept up in the beginning of March Madness.
Basketball fans in Williamsburg gathered at bars like Croxley's Ale House to watch the 16 games played throughout the day.
According to Wallethub.com, around $2 billion is lost every year from sports gambling during March Madness.
The three-week March Madness period is also considered one of the least productive times of the year, due to people calling out sick to watch games.
The NCAA basketball tournament ends April 4.
