73 years ago my oldest brother hit a hole in one here in the moat at San Juan, Puerto Rico’s El Morro fortress when it was a 9 hole golf course on the grounds of the US Army post of Fort Brooke.
The tee box was at the upper far end, and the golfer had to drive the ball over the bridge - doglegging left (towards the right in the picture) to the sand “green” which was out of sight.
The caddies would sit on the bridge to signal to the golfer how well he/she had done.
My brother’s caddie got so excited yelling & waving his arms that he almost fell off the bridge.
In the 3.5 years we were stationed at Fort Brooke, it was the only hole in one scored on that particular hole.
General Bathers’ (the commanding general of the Caribbean Antillies Command) wife, an avid golfer herself, painted a nice water color picture of my 14 year old brother’s feat….and it included the Puerto Rican caddie waving excitedly on the bridge. The picture still hangs in Brother’s home office.
