And a few more details from the Morning Call...
COURSE* Several short par 4s
* Four par 4s that measure 490 yards or longer
* One of the two par 5s will stretch longer than 600 yards, and both par 5s will be among the first four holes
* "We've narrowed some of the fairways, moved some bunkers and lengthened the course," Ill said. "We'll be tweaking the course between now and next year, but it's essentially ready."
LOCKER ROOM/PRACTICE FACILITIES* Players' locker rooms and practice facilities will be located on the West Course, with shuttles running the mile in between.
SITE/SPECTATORS* Grandstands to accommodate 17,000 fans, hoping people fill those seats to alleviate course crowding
* Merchandise, concessions and restrooms will be located on the course's perimeter
* Off-site properties such as neighboring Haverford College agreed to host the hospitality tents
* Bridges will be constructed from Haverford to the championship site
* "Corporate tents will take over some grounds of the posh neighborhood."
NEIGHBORHOOD* Residents who live on Golf House Road adjacent to the course are giving up their lawns to the championship
