I was just in our local book store and noticed MC on the front page of Women's Weekly (actually it was dated august 10 2010, not that recent) with his dog Tina. He mentioned that his daughter was in the new horsepower docu. but didn't spot her, did anyone else see her in a segment.
He also mentioned that he was playing snow polo in Colorado but that wasn't in the series either. May be there will be sections not show for TV in his DVD if they put one out. I know I was in the UK when IslanRAB of Britain was shown and it was in the stores straight away as I bought one while there.
Regarding the question of filming in PI may be Kernow knows whether they are scouting around for a new "doc's house" as that one would be too small for a family. I could just see the Doc bouncing the pram down those steps....
