Rainy seasons usually starts at the end of October, but we're talking about Africa so you'll never know.

I'd been in lake Natron in August '00 and I finished with the license 5 days before (of 15 days hunting). Just 20 animals in 10 days, including Lesser, Gerenuk and Oryx. In this area only there was mountain buffalo, 5 hours away from the camp and small trophies. I didn't try them.

A tip: Be very patient with Lesser Kudu, they're there everywhere, just wait for the one you want.
