Video: The Mood For Merion, 8th Hole Flyover
/With no room to lengthen, the 359-yard yard 8th remains a drive and pitch holes as it's been since the day of Jones. In fact an aerial depicting Bobby Jones' tee shots from the 1930 U.S. Amateur show him driving to fairway just in front of the green, a swale that is now rough based on this aerial posted by the USGA and presumably shot last year.
The video also notes that this hole is a candidate to be shortened to tempt the players into driving the green. It's hard to tell from the aerial how wide the throat is that Jones drove to, but with the hay-like native grass visible on both sides and a front bunker it's hard to see how someone would be tempted.
