Everyday a troop of vervet monkey's is patroling the campsite to check if eveybody closed their tent/lodge/roundavel. If not, they go in and will take everything that is eatable. It happend one time to me and I can tell you, they only need a very small hole!
When I am in my safari tent and just listen to the sounds of the bush, or walking around a bit, to the reception for instance, I feel the power of nature. It makes me feel small in this world because every moment a dangerous animal can approach and change your life forever.
I also did a walking safari with an armed ranger just after we spotted a big male lion. We drove some minutes in the oppisite direction, but it was a very excited moment when we climbed out the car and walked away from it, only to come back several hours later!
