Wonderful photos, Ian. Keep em coming!
Tell your wife not to worry about the elephants. I was fairly close to them in Kruger yesterday (within 10 meters or so), and found them to be quite passive. They will warn you if you're getting a bit too close. Just remember.... stay in your van! You picked a great time to visit. I saw well over a thousand animals during my 8 hour drive in the park, and was fortunate to see all the big 5.
Last night was a great pleasure meeting up with Willem in Sandton. You're in for a real treat when you get to meet him in a few days! Keep your wife away from him: the women really do tend to swoon over that accent
I'm off to Namibia in a couple hours. Looking forward to it.
