IRELAND . . Castle ..Hooray! . The dream empowers me, the bike and I are joined! We spin through turns and rise over hills like a bubble in a stream, tunneling through overhanging trees, wind and sun at my back. A second-wind, a flood of endorphins kicks in. I'm strong, surely will ride over a hundred miles today. An enchanting fairy-tale castle looms like a great apparition above the treetops, with turreted towers, moat, and drawbridge. Irish can't afford living in such costly digs. The gateman tells me a wealthy Philadelphia family rented it for two weeks.
