bobbyg, I asked because in Patagonia Argentina is -depending on the area- is relativelly usual to see puma (cougar) tracks. Very smart animals they can spot you during hours and you not them. Some males are really big (200+pounds) and the attacks to humans are unusual but I know that in US you have had several including very bad ones. Not bears here thanks God. Poison snakes are problematic in some areas at North (Bothrops species, Yarar?) when we go for dorado.
