Kenya's Aberdare National Park, about 100 kilometers north of Nairobi. At the Ark's

prow(船首) are huge windows overlooking a waterhole. Earlier tonight, I'd watched a

pack of wolves, buffalos and elephants. And now, at three or so in the morning, I'm

down for rhino bells. The first time, 2. 5 hours ago, it was a single black rhino, which

came down, got a drink, and left.

I'd have been sorry for the lost sleep. I've already arranged with a guide to take me

out at sunrise for the so-called "should_never_miss" bird-watching, where we'll get to

see 30 species, but really, how many times in your life will you get to wake up and say,

"Wow! Rhino!"? Isn't that the definition of a pretty good night? Last week we went

from Uganda into Kenya. Before I left home, 1 thought I'd be happy with ten elephants

and five or six giraffes on the whole trip. I didn't dare to dream the rhino.
