Have you seen the video of it.  I think just saying its boardwalk is underestimating it a little.  Granted the guy on the video is bloomin fast but it looks like its gonna be an amazing rush for people who havent quite got DH skills but still want the thrill of coming down a big hill fast.

I suppose it should be as close to riding somewhere like morzine etc as it will get in this country without full on DH rigs.
