And while not a golf experience, watching the Yankees come from 9 back to beat the Sox by 6 was a great experience!
In that vein, going to have to say that watching the Sox overcome an 0-3 ALCS hole on their way to the Series is up there.
Golf wise:
The complementary scones at Royal Melbourne (simply symbolic of the entire experience).
Having to shoo the Wallabies out of my way on my walk from the cabin to the clubhouse before my first round at Barnbougle.
A Guinness at the turn at Kingsley, and a mailbox visit before playing the 18th.
The history in the club house at East Lake.
The green chili at Ballyneal.
Driving past the Yale Bowl (scene of many Saturdays from my youth) before pulling in to play the golf course for the first time.
Taking an evening to explore the beaches south of Bandon (the town).
Seeing the smile on the face of my caddy (the best of the trip) after my last round in Ireland after gifting him a Master's hat.
Any course were the rising sun shows a perfectly undisturbed light layer of dew, meaning there's no one out ahead of you.
