I've actually been to that spot Jaws ollied and the footage doesn't do it justice, like most huge sets. The runway is no more than 2 ft wide and you have to push with your foot behind the board. Not to mention, on the other side of that small rail up top there is a 30 ft fall into the river. Not to mention you don't know how shallow the water is and there was a bunch of large branches and other shit that was floating below.
Long story short, not only is it huge, it's fucking dangerously sketchy. Pretty safe to say Jaws will be the only person to ever ollie it, let alone get a trick down it. If anybody does do a gap or stair, longer or taller, it seems irrelevant cause the consequences of this thing are gnarly.
