Many ports around the world have nothing but bike racks lined up for access to the pier. And a dude to check cruise cards.

And in the old days at st thomas and nassau you used to be able to walk up to the gangplank and get a tour of the boat.

Used to be no big deal to walk the piers but times have changed.

I guess thers always somone to be afraid of.
