(Continuing to answer Dean's question - why Costa Rica? What did management plan to do down there?)
Interestingly enough, this was the heady time of the first "Ideal Orgs" and we still believed that infinite, "straight-up-and-vertical" expansion was in the works. Especially all of us outside Int Base ('the other 99%') who didn't know that COB

was beating people up mercilessly for... (what was that for?)
And in this time, it was decreed that all orgs everywhere shall expand, and that Central America shall have a Central Ideal org to service all the countries of Central America and its feeder Missions.
I was the first DSA ever (to my knowledge, anyway) assigned to function as a "fully-hatted" DSA for a Mission. And when I arrived, a "mission" was underway in the Mission, "on a mission" to find this Ideal building that the public of Costa Rica were going to fund.
Oh - and I left out the part about the fact I had no intention to renew my 2003 contract wrapping up 10 years in Dallas. But... my lovely new wife brought me before the ED of the Mission on my Spring Break trip of 2004, and, well, they needed a DSA in order to go "Ideal" and well, I signed up - ("Duty" being high on the scale of motivation 'n all - and more importantly by now, having a happy, beautiful wife was several notches higher than anything appeared on Hubbard's motivation scale)
I was designated (never in writing! - just in secret meetings top floor of the HGB) - "DSA Costa Rica" - an implied promise that "Org" status was "just around the corner" for Costa Rica.
My job was to take charge of all Central America and its Missions, and get it ready for the new "Ideal Org" that was promised for the capital city, San Jose, where my wife and I lived and the Mission was established.
Some notes on being Costa Rica staff:
*people there were very pleasant and friendly :wink2:
*it was very refreshing to see people read policy and actually "do what Ron says" - I was accustomed to doing it like DM told Flag to do it, from trainees coming back sternly warning you, telling you "how we do it"...
The above two points lasted for the first few years, until trainees started coming back from Flag. 
Then we learned that what Ron -really- meant (he said so in a tiny paragraph in the middle of an old 1963 Red-on-White) was that AT THE ROOT OF ALL YOUR ARCx's (upsets) WERE YOUR MISSED WITHHOLDS (crimes) so therefore that's how we did it at Flag, and that's how we'll do it here. Your ARCx's are nothing you wimp - it is all about your overts...
SCIENTOLOGY AMERICAN STYLE (DM's serious, cold-chrome-steel version) - that which I had fled in horror, as the Ideal Org strategy rolled out - had finally arrived to COSTA RICA
But I am getting ahead of myself, here...
