Just back from South Africa on a trip of a lifetime... except we loved it so much we have to figure out a way to do it again!
We were on our honeymoon, but fortunately my wife was extremely patient with my need to keep the shutter clicking. I was just blown away by the quantity and quality of wild animal sightings.
Have a browse for a taste of Africa:
