Man, this is the stuff of dreams! How I would have loved to play the day before the open. The closest that I have come to this was when I played a week before the South African Open on Royal Cape in the Western Cape. The tees used for the championship were obviously restricted and closed off to the players, but we teed up as close as possible to them. It is crazy how good these guys are; we struggled to break our handicaps on a tour-manicured course.
In any case, I hope you manage to play yourself into that round! Are you playing another round or is it based on this round? Best of luck, my friend! Keep us posted. Next time the putts will drop.
