I was thinking that the by boat part referred to the Statue of Liberty. Then it said go to shore then southeast in a subterranean passage, so I thought it could be there.
I don't have time to try and figure this out, but I'll definitely check back to see what the answer is.
I'll step in here and say that it refers to "can you get there in time to stop the murder" That's all.
No, simply because if you don't know how to post a screen shot, you can still link to an "image" of it. It can be seen in google maps street view and that image can be linked
