Hi, I'm Ken, an American residing in Thailand. I'm old enough to be your dad, but have been thinking of taking a trip to Namibia. My main inspiration is seeing photos of the sea coast with wild animals roaming around. I like to trek off alone in canyons, so it's probably not much suited for Windhoek, but I would likely go through Windhoek on my way to secluded wild places elsewhere. You're welcome to email me with ideas:
ken@adventure1.com thanks.
