The Ryder Cup 2008 will be played the third week in September at Valhalla Golf Club in Louisville, Kentucky. Tickets to the event were sold out long ago. They are, however, still available at My Ticket Market. They are expensive, ranging in price from $147 for a one-day, general admission pass to $1,320 for a four-day – 18th through 21st of September. Obviously, I’m not recommending this source, but it does seem to be one of the few places where tickets are still available.
