This is one of my favorite shots. Good friend Sarah West took it when I passed through London on my way back to the U.S. after a German seminar tour.
Who could resist taking a photo with such a gorgeous animal? My wife would say at this point, "And the horse he's sitting on, too!"
It also goes to show that H.R.H. Palace Guards have not only a finely tuned sense of humor but also extremely good dressage skills. (That's the ability to direct a horse with tiny, subtle movements.)
How do I know?
