According to the New York Times, this is the "world's largest home-built skateboard ramp" -- located on Bob Burnquist's farm in the San Marcos Mountains (San Diego). Video after the jump.
The ramp soars eight stories high and is longer than a football field. Professional skateboarder Bob Burnquist built the ramp for $280,000 on his 12-acre farm. The ramp is for professional skateboarders only -- it is not open to the public
