I noticed a while back that south america gets ignored in most worldwide conversations. Especially in the realm of military conversations.
For that reason, I think the further south you go in South America the better you’ll be.
When I discovered that, it kicked off a mini-fascination with South American and I spent lots of time researching the Beagle Channel and the towns that line it like Ushuaia. Drop yourself in there with Google Street View. Pretty fascinating little corner of the world.
