Quiz: Wednesday is opening day--and the 100th birthday--of the 27-hole A.W. Tillinghast course on the Delaware River at Shawnee, Pennsylvania.  Beautiful layout, what with most of it being on an island right in the river (and within Delaware Water Gap National Park, no less). It's also one of only two Tillinghast courses in the U.S. open to the public, so... Where's the other one? http://bit.ly/8ZYxZj
