I tend to agree with most of both replies there.
I used the word "decorative" to describe the bushes I think that might be part of the answer. So far as I can establish they're guidelines to assist the jockesy many of whom were taking the wrong course when it was first introduced. They serve no other purpose. I tend therefore to agree with Flame, and personally I wouldn't mind seeing some of them selectively removed, and reckon it might actually add to the spectacle of the race, if it starts to place a premium on jockey tactics and becomes a free for all. Like I said, there's a bit of the old romantic side of steeple to steeple about it, which if the cross country course can come to embody some of this heritage and challenge jockeys to pilot their mounts round drawing on ingenuity and a bit of 'seat of their pants' riding, then I say why not?
Colin, there are white boards round the course that look like an old stoolball target. Mick Fitz knew immediately when it was suggested that he'd taken the wrong course. He pointed out that the rules state that you have to ride outside of this board and the slow motion shown afterwards clearly showed he'd done this. Fitz also went on to explain that the bushes are guidelines only, and that in his imo Russell was quite within the rules to cut the bend once he'd cleared the board on the outside. Luckily for him he didn't have FIA stewards to answer to!!!
Alice interviewed Russell straight after and Davy was confident even as the claxon sounded. He said he'd walked the course, spotted the short cut, sought out the opinion of the stewards declaring to them his intention to ride to this strategy and was told it was legal to do so. Not surprisingly, he kept this info to himself. Why should he share it? It's his improvisation and ingenuity that allowed him to spot the line, so its fair enough that he should benefit
