Easy. Just the one Hole-in-One for me so far. It was probably the best 3 wood I’ve EVER hit in my entire life. It was on a “boys weekend” based in Cascais, Portugal. The image below shows just how challenging the hole is. The 5th hole at Aroeira II is 220yds off the White Tees it was about as well as I could hit that particular club.
The only disappointment was that there was a false front to the hole so I did not see the ball go in the hole.
