It had been so long since we had visited the Seattle Aquarium (have I even visited before?) that I did not remember whether the Oregon Coast Aquarium was equal, better, or worse. Nevertheless, the clear star of the attraction, judging by the 4-year-olds pressing their noses against the glass or the kid excitedly dragging his grandmother to hunt for the elusive wolf eel, was the underwater tunnel. Even I, admittedly, was entranced by the sea life passing above and below me.
