What might amaze you even more is that high above this busy harbor there is something special. Yes, a sky train I guess you'd call it. Anyhow, small basket-shaped cubicles carry up to four or so people along on cables that stretch from the mainshore out to a nearby island a few miles away. Maybe it's best described as a ski gondola situation going over the water instead of up a mountain slope.
Many of these boats plying the harbor en route to various outlying islands had life preservers tied on the roof though I didn't notice any anywhere on this particular ferry.
