Heavy security surrounding the suburban Houston site for the NFL title clash between the New England Patriots and Atlanta Falcons shut the door on tailgating as fans had to park remotely and ride buses to the 73,000-seat stadium.
But ticket holders were already in full party mode after a dizzying weekend of high-energy fun in the city centre by an estimated 140,000 out-of-town visitors that poured in and those able to make it to the private parties dotted around the Texas oil capital.
There was something for everyone, from the NFL Experience that catered to family fun, to booming dance clubs.
A-listers, movie stars, and business titans filled VIP parties across the city, from the Maxim bash to the Taste of the NFL, which benefits the homeless, to the exclusive Bootsy Bellows soiree in a private club tucked in a corner of downtown.
