Mike Rhodes climbed Mount Kilimanjaro a few years ago with his friend, Scott. 

Mount Kilimanjaro in Tanzania is the highest peak in Africa and the world's tallest free-standing mountain. It's also the world's tallest walkable mountain—and what a walk it is. To reach the summit, one must pass through five distinct climate zones ranging from rainforest to alpine desert and eventually glacial Arctic. Although it is possible to climb Mount Kilimanjaro without any specific mountaineering training or equipment, summiting the Roof of Africa is not an easy task.

Approximately 25,000 people attempt to summit Mt. Kilimanjaro annually. Approximately two-thirds are successful. Altitude-related problems is the most common reason climbers turn back.
