In general, I found that the seemingly random mounds of long grass in the fairways worked, as the fairways are quite wide and, at least after one play, I suspect it is easy enough to avoid the mounds with well played shots. The one exception was the tee shot on 18, which I thought was goofy with so many mounds scattered here and there that it seems almost impossible to do anything but blast a tee shot and hope it does not end up on of the mounds.
Though some folks may be bothered by all the mounds in the fairways and others (me included) may think the greens are over the top, there is still a lot of very good things about the Castle, not the least of which is some of the amazing views. Standing on the front right side of 6 green looking at a back left pin position, with the town of St. Andrews directly in view across the bay, is one of the best views I have ever seen in golf.
