A tropical landfill
I've been to Guam with the military. While I can't speak to the ATR flying out there, I did meet someone who was with Cape Air at the time and seemed to like it. Now about Guam: it's a tropical land fill. While it used to be a vacation spot for tourists from Japan - and still is - the numbers are not what they used to be. Entire hotels are closed due to Typhoon damage, SARS scares, etc. There are cars all over the island sitting on the edges of the road with TREES growing through them because the government never cared enough to move them. Others are rusted hulks, and some have been burned. There are what appear to have been nice homes at one time with no windows or doors - I guess they were damaged with the hurricanes. All over the island there is trash along the roads. It appears as if the government hires someone with a bull dozer to shove the garbage further from the road and into the tree-lines, where it piles up. I saw people living in tents there just off the highways.
So - while I wouldn't want to actually live there forever, I suppose it would be great place to fly for a couple of years - easy to visit exotic places in the far east, and the ATR is a good airplane. Good luck.
