Yes it was lovely to see her - she has the most beautiful smile which lights up her face.
I guess she made a special effort as her granddaughter Lady Louise was driving the trap drawn by the Fell ponies (the trap/carriage was owned by the late Prince Philip). I understand that Her Majesty had 14 ponies and horses entered for various categories at the show - and one won first place, with the Queen being presented with a cup! :)
