Having visited Gleneagles last Winter to meet with Tommy Cushnahan (fellow MSc grad from Edinburgh and David K's man-on-site) I was impressed with much of the work.
DK appears to have seen more in the site than Mr Nicklaus did. There is already a brand new 7th Greensite way over to the right of the old one. New bunkering on 8, much more interesting use of the wetland in front of the 6th, and - THE KICKER - the removal of the HUGE bunker on the Par 3 4th - 'The Gowden Beastie' - now more The Green 'Kidd'er! (I don't think Mr N will be too happy).
Lots more to be done I believe over the coming years. Who knows, maybe it will equal the Kings one day...
FBD.
PS JK - wash your mouth out with soapy water, man - you know how good Scottish Parkland courses are!!!
