Cruise Ship Rockin' & Rollin'

The Pacific Sun swayed a little 'to & 'fro while on a recent voyage! Watch the video and see chairs, tables and people sliding around on the ship! (And watch the lady on the far right of the screen as she stumbles towards the left side of the screen, slams into a pole and gets knocked unconscious.)
