Panam? I can understand. The whole Darian Peninsula has not been completely explored..and is filled with some real nasties...
DR? Yes, I can see where being set down in the middle of the Central Mountains could be a challenge, due to the lack of things to eat and drink...people have been lost up there..however, for Bear, a half a day's walk North or South and bingo: Civilization such as it may be...
Haiteses>? Ummm, maybe....Mountains in Neiba>? Cloud forests, so it could be interesting, but not all that difficult to survive.
Now, getting from Montellano to Blackbeards on publicos without losing your wallet or virginity is really a challenge...
Good one!!
