Frank, is there any way you could label all of those photos in some form or fashion? Your site has the potential to be an amazing resource, but I have stopped visiting it because for all of the photos on the site I don't know what I'm looking at (apart from which course you're talking about, of course). Ideally you'd be able to match each photo to a hole number - "7th hole, photo #1", etc. - but even if they were simply labelled numerically, Tom could have cited that number in referencing the photo so we could tell him which one it was without having to look through literally hundreds of photos. (The site would actually be more useful to me if there were only 2-3 pictures of each hole on a course, as it'd be easier to tell where one hole ended and another began...at the moment, the site is just full of data that doesn't really tell me anything, if you follow me.) Just a few thoughts - hopefully helpful ones!
Anyway, I posted my review of the Castle Course here a few weeks ago. I can't say the color of the bunker sand struck me as being unusual, although I don't think I was in a bunker all day, so perhaps I'm not the best judge on that score. The fairways are all very wide, so the long-haired mounding doesn't come into play as much as you might think; a good player should be able to steer well clear of the mounds, even the ones that appear to be in the center of the fairway. And the greens are wonderful - so much fun to play, many reminding me of the better greens at Machrihanish (like the 2nd, 6th and 12th). It's well worth a visit...it's in the same class as Kingsbarns, I think, but even though both courses have similar origins, they play and feel much different to one another.
Cheers,
Darren
