Not really outside the US as Guam is a US Territory, but definitely a different world than stateside. We were stationed there for 2 years and I loved it. Had to learn to get used to all the meat being frozen when you purchased it. While we were there a stateside dock workers strike kept the BX/commissary from getting in any paper products for what seemed like a really long time. Didn't realize how much paper we use all the time until then. Discovered that typhoons give you lots more advance notice than tornadoes. Actually it was only considered a tropical storm when it went over us, but it did continue to gain strength before hitting the Philippines as a full blown typhoon. By the way, typhoon preparedness includes knocking all the coconuts down out of your trees.
A few amusing incidents - #1 - DH and I were driving around the south end of the island where many locals lived. As we came around a curve we saw a water buffalo tied to a fence, then as we got only a little farther down the road there was a house with a Corvette in the driveway...the juxtaposition of such diverse cultural sights so close together was really striking.
#2 - Driving down the road and having to slow down for the Nissan pickup being used as a gravel truck.
#3 - I decided I'd been on island too long when I was driving back to Andy South (our housing area) from Big Navy (the base at the other end of the island that had the larger BX & commissary) and saw a cop downtown with not yet tanned skin and thought 'that's just wrong'!
