This topic came to mind as I was plummeting toward earth on the Magnum roller coaster at Cedar Point with my eyes closed:
Is it possible for a blind person to have a fear of heights? Not knowing what it looks like from 205 feet above ground, is a sightless person able to grasp the immediate (perceived) danger of falling from the edge of a cliff or, g*d forbid, the summit of the Magnum roller coaster?
