Re: Stop the horns? Yikes!
I Don't think I've ever heard the Hudson River ferries use their horns when backing out of their slip. I know it wasn't used the last time I took it from Weehawken to Mid-town. The SI ferry uses one blast as it goes forward in both directions. I'm trying hard to remember if I've heard the East River ferries use theirs, clearly they are now.
When I had a slip on the Hudson the helicopters created more of a constant drone than the ferries
