Well I am one among the lot! It was hard to digest for me when I saw the two horses whom I bet on for the very first time, took the first two places...and I was still walking from the place from where I had clicked him when they finished. It was an amazing feeling. For some reason a thought did strike me - my fellow humans, whom I (we) count on let me (us) down many times.
But still I wonder, how can we call - A combination of strength of the marvellous beasts together with the smart & hard working jockeys - FORTUNE! Believe me, you would not be happy to have the diet of a jockey, it really sucks. And they sacrifice so many things just to be on top of their fitness & be light, so that their horse can accelerate quicker. "Sea Biscuit" impressed me immensely and I have been a fan of both the beast and its master since then.
NOTE: If I am asked for one of those snaps that am really satisfied of, it would be Run For It... . It does'nt look that hard but you have only split seconds to get the frame you want [though a bit of fortune is required]. You cannot feel it unless you try. If you have not seen the movie, see it - for it's full of amazing spirit, bond, trust, picturization & strength.
