While most of the cruise industry’s more obviously ramped-up security measures have focused on screening passengers as they enter and exit a ship, cargo, too, gets the once over. Or even twice. Last week in Hawaii, two bomb-sniffing dogs picked up a suspicious scent on a couple of boxes waiting to be loaded onto Crystal Harmony. Officials there quickly shut down the entire harbor for three hours and called in the FBI and bomb specialists. Alas, it was ultimately determined that there were no explosives in the boxes and the Honolulu Harbor was reopened.
