Adam,
If grain is going to be a factor with the green, the grain will point towards the sun and down slope. Some golf courses (and very few) manage for a little grain, most do what Donnie stated. Grain is not a factor in putting these days unless the superintendent is not managing against it, which may be what the owners/members want. Remember, the longer the blade of grass the deeper the roots are able to grow, even when the blade is laid over.
Because superintendents have been managing against grain and have eliminated it may be the reason why we are having troubles these days with moss, dry spots, weeds, and other problems.
GCA members should be a group promoting a little grain on the greens. A player that is able to read the grain and compensate is the better golfer. By eliminating the grain on the greens, we have succumbed to golfers wanting easier golf courses to play. Much like the high water and fertilizer treatments have done.
