Haven't hunted them, but I have hiked in the Floridas; they will get you breathing hard, and they are rocky and noisy. Getting an ibex in bow range would be quite the feat. I talked to a guy there once that was bowhunting them, and he had busted his butt (according to him) for several days, and had yet to see an ibex, let alone get in range of one. Should be a tough hunt, but a trad ibex would be a real trophy.
January can be surprisingly cool there, and a warm October could mean that Mr. No Shoulders could still be active. Lots of rattlers in that country.
