Harry can summon his Firebolt when he battles the Hungarian Horntail, but he can't transfigure a rock into a flying broom (as Cedric transfigured a rock into a dog).
Yet flying broomsticks and dragons are not cheap.
I like Harry Potter very much, he is an excellent actor, he is very handsome, have on a pair of glasses with black frame, I am envious of his flying broom, I hope that I can get off the ground one day too!
