"Design isn't the main cause of slow play, but it certainly contributes," Doak says. "For starters, modern courses are too long. It takes golfers more strokes to cover that ground, and they still have to cover all that ground even if they aren't playing from the back tees, just to get to their own tee. Plus the very existence of those back tees convinces you and me to play the course at 6,500 yards, where in Scotland the back tees would be 6,500 yards and most of us would be playing from 6,000.
\n"Second, many modern courses have too many bunkers. Getting in bunkers and raking your way out takes a lot of time. And third, a lot of modern courses have areas of long grass bordering their fairways. That long grass may look good in pictures, and it may be environmentally friendly, but if it's too thick, people are wasting lots of time looking for their ball in the rough."
