How do you fill an arena with dirt? One truckload at a time.
It's not quick, or easy: It took 170 loads to cover the floor of U.S. Bank Arena (with 3,000 TONS of dirt) in preparation for this weekend's AMSOIL Arenacross, the opening round of the 2016 season.
What's Arenacross, you ask?
Well, do you remember Excitebike -- that motorcycle jumping/racing game for the original Nintendo? It's that, in real life.
If you want to see this weekend's Arenacross events in person (after reliving your Excitebike glory days), you can get the full event schedule and tickets here.
And watch the time-lapse video above to see how, exactly, all that dirt got into the arena.
