I wrestled with the idea of hiking to see the gorillas of the Virunga Mountains in northwest Rwanda. On one hand, an African safari was high up on my bucket list and going to see the gorillas in their native habitat would be nothing short of spectacular. On the other, what would happen if one of these critically endangered animals acted in a way that's only natural if, for some odd reason, they felt a member of their group was threatened by one of us?
