We are roughly 3 1/2 hours flight time from Japan (due SE). The military exchanges bring in some cool stuff every now and then. I’ve bought my T at AAFES (Air Force) and the Coolpad at the NEX (Navy).
I was once seeing discovery channel and they were discussing some kind of snake from guam (brown tree snake if I’m not mistaken) and they would actually reach other countries by getting into the cargo compartments of planes (most of them probably died on the way )
Indeed, the brown tree snake hitched a ride into Guam and pretty much decimated the whole bird population. It is also blamed for power outages by getting tangles in power lines.
