I got a vibe from that clip that most of the people we`re just wathincg the rail and stairs. Whenever someone landed something on the rail or the stairs there was a big crowd of kids going "yeah" and when Arto did anything on that transition there was like 3 old school pool dogs going "yeah".
By the way, the best trick in the whole clip was Rowleys switch bs 360 powerslide. hardest thing ever
