I hope you aren't assuming animals are roaming streets of Africa. I live 60km away from Kruger National Park but have never seen an elephant strolling down a street. Majority of us also go to the zoo to see elephants, just like everyone else.
I was just in Kruger last month. Why on earth would you go to a zoo if you live so close to it?
I keep on postponing the trip. I always tell myself that I will go next year. Been postponing for 20 years now. People who stay closer to something rarely values it. Most people closer to the national parks will pick Eiffel Tower over going to the national park anyday. Vice versa.
