I well remember my first, #17 at Oakmont which made it also my first albatross.
That hole was also the final one in my only ever sub 50 round earlier this year. Obviously a custom course and I needed to play the last 3 holes 7 under to do it. Eagle, birdie, hole in one eagle on PB# 7 (I think 7 anyway, the 109 yard one with a 30ish foot drop). Drove the green on the last, Oak #17, and made a putt from about 15 feet for the 49.
Sure was a great feeling and 2 days before my 50th birthday too : )
