I did read in ONE interview of one of Ann’s friends (back in 2007-2008) that Stanley Ann spent A LOT of time( while being stationed in Indonesia) in the Philippines. Whatever for, the friend didn’t say.
The only evidence or connection I remember between SAD and the Philippines, from reading on FR, is some kind of (curse my bad memory) - a visa application, or some kind of passport form - and mention of a Philippines visit, but IIRC it was proposed, not necessarily accomplished. My memory is just not serving me well.
