Of the two choices presented by the OP, I would choose Cape Buffalo.

However, there are multiple species that I would consider as more worthy of the "Once-In-A-Lifetime" title. Coincidentally, most of those are also found in Africa - Mountain Nyala, Lord Derby Eland, Bongo, and Roan make my list. Marco Polo Sheep and free-range Alpine Ibex would be in the running, as well.


I'm becoming more tolerant of intolerant people.
