Got to take exception to that memorial plaque, however good the intention. In what religion would the "souls" of the dead be entombed in the tunnel? The bodies, OK. But even to us Atheists who believe in souls, they don't hang around. Christian souls, Moslem souls, Moron souls, off they go to meet their maker. Atheist souls, and some Jewish souls, simply stop. But hanging round pointlessly (switchlessly in the USA I suppose) makes them not souls but ghosts. That's a bad loss of status.
