Damn! Do you have any more pictures?
Here are a couple more...
The first is of the boat we rented. The second, another shot at the lake. The third is of the Kariba Dam, which makes Lake Kariba a Lake. That's Zambia on the other side of the dam. Another reason for the guide is that you can be arrested and boat confiscated if you wander out of Zimbabwean waters. Of course, there was no way of knowing that you did, as we had no charts or navigation instruments. Our guide was invaluable in that regard.
On another note, concerning the first couple of pics I posted above, there was no filter or photo manipulation on those shots. It really looks like that. I have never been where I remember the sun being so intense. Daytime temps peaked a little over 100 F. Our guide was motoring the boat when we came upon those hippos in the trees. I wouldn't have had the nads to get that close. His piece of advice was never get between a hippo and the water. Hippos kill more people over there than lions do. There were lions in the area, as well, but we didn't see them.
The boat had a net between the amas that could be lowered down for a swim. I was quite happy to do a bucket bath on deck, though my wife and daughter followed our guide's lead in using the net. Now, we had just seen crocs in the water not 10 minutes before they dunked. Luckily, her life insurance was up to date! I watched for crocs...
My daughter does nutrition research in Zimbabwe, and is there much of the year, so we had a first rate tour guide. She ferried us all over the country to various federal parks when we were there. The county is beautiful, and the people are wonderful. The roads and infrastructure, not so much. What would be a moderate trip by car in this country, would be an epic adventure there.
The last pic was taken in Hwange National Park. That particular bull was telling us "close enough" with his ears. Any closer, he would have charged. Unfortunately, there have been instances in Hwange where poachers manage to poison groups of elephants just to remove their tusks. These guys don't forget when humans do them wrong, and can be very dangerous.
