If you search around, you will find that first double eagle occured almost 2 years ago. We waited at least a year before another one was hit. Now, a reasonable person would ask, why so long? Explanation is very interesting and probably required 1:1,000,000 shot and initial skid drive which was pretty hard to achieve as well. With such odds, hitting royal flush is easier.
Reason I am posting this, is this: earlier today, I hit my drive, and was late by a line,which allowed the ball veer right and land in same spot that we used to land to skid to get to that distance.
That was the only way that shot could have been gotten. Replay of my drive is here
Now, to get the double eagle, from the old days, you had to hit your 215 3w and either get some nasty side kick from left or approach from right. From right it's impossible, so only reasonable approach is from left.
If only we had a replay of that shot!
