Watching a group of lions stalk and take down a wildebeest would have to be one of the most breathtaking dramas I've watched. That is not on the same physical scale as viewing the Grand Canyon or Yosemite Valley. I've hiked to the bottom of the Grand Canyon a couple of times, and to the top of Half Dome in Yosemite a couple of times, which deepens, or heightens the experience,you might say. I'd like to tell you about the view from the top of Mt. Kilimanjaro, but I was suffering from high altitude cerebral edema and could not see it very clearly. Diving the Blue Hole in Belize was a magnificent experience. Walking through a forest of giant redwoods is humbling. Watching lava flow in Hawaii is incredible, and watching new beaches being formed by waves pounding the new lava day after day. But there are many natural wonders on earth I've yet to see -- calving glaciers in Alaska, trekking the Himalayas to gaze up at vast peaks, the splendor of Victoria Falls, Iguazu Falls, Niagara Falls, the Amazon, the giant baobab forests in Madagascar. The world is filled with amazing wonders to see, how could I possibly pick a single one?
