But aren't all great quests folly? El Dorado and the Fountain of Youth and the search for intelligent life in the cosmos--we know what's out there. It's what isn't that truly compels us. Technology may have shrunk the epic journey to a couple of short car rides and regional jet legs--four states and twelve hundred miles traversed in an afternoon--but true quests aren't measured in time or distance anyway, so much as in hope. There are only two good outcomes for a quest like this, the hope of the serendipitous savant--sail for Asia and stumble on America--and the hope of scarecrows and tin men: that you find out you had the thing you sought all along.
