What happens at a soccer tailgate?

The tailgate is a traditional part of the American sporting experience.

In the car parks surrounding sport stadiums, fans set up hours before the start of football, baseball or basketball games. You could call it the ultimate spectator sport, with eating barbecue and drinking cheap beer the only real rules.

But the tailgate is also an increasingly popular part of going to a soccer match in the US. During BBC Pop Up's month in Tucson, Arizona, Benjamin Zand went to find out how these parking lot parties differ to the American football version.
