Doc and Marty land in the middle of a fli-derb game.

A fli-derb is a roller derby using advanced hoverboards known as fli-blades.

The 2035 Fli-Derb Western Regional Championships were held at the Lone Pine Fli-Drome in Hill Valley.

On September 16, 2035, Emmett Brown and Marty McFly traveled from 1986 via the time parachute, and smashed through the Lone Pine Fli-Drome's glass ceiling into fli-derb arena itself. They broke another window as they made their escape on a stolen fli-blade.
