That made me chuckle hrprof. Yes, I think you would qualify in the "serious nature and wildlife watcher" category. I dont think I could spend 4 days watching one pack of wild dogs. I think some of us may turn into wild dogs if we were in that jeep with you for four days.
We started in Amboseli - vans with open tops. We also saw a lion kill a zebra from start to finish and then bring the cubs to feed. All from Amboseli which is "on road" only viewing and lots of vehicles. Still a tremendous experience.
Then we went to Masi Mari - Kichwa Tembo
We did watch a male lion approach a female lion for a long time and it was fascinating. This was in Kenya and there were a lot of vehicles watching this but this really did not detract for me at all. Then the rain came and I guess that is a "cold shower" for a male lion the excitment was all over.
I will say that as we moved from Amboseli to Masi Mari I far preferred Masi Mari. I dont like the "on road" aspect of Amboseli, the jeeps and off road driving is far superior.
With all your experience in Africa I can see you preferring the "Botswana" experience.
