This picture was taken at the 1978 skateboard contest at the Everett Skatepark which was housed in an old ice skate rink (not frozen). It had a long mini-ramp section, short mini-ramp, a half-pipe just to vert, and a quarter pipe. Everything was plexi-glass, except the quarter pipe. Pipe coping on the mini's only.
360 at the Everett contest. They called this the "banked freestyle."
