Complaining about the change in culture, or longing for previous times, is a fruitless endeavor. The culture is what it is, and it will not change or go back. Perhaps professional golf is to blame. Amateurs who watch the pros consequently do what they do, whether it's plumb bob, buy a huge putter Jack used in 1986, twirl the club after a good shot, or spend time figuring out their distance and what club to use. If the pros spend forever getting ready to hit a shot, then why shouldn't I?
Yes, some guys like Rory McIlroy and Rickie Fowler are quick, but they are the minority and the pro culture will not change. Therefore, the culture for the rest of us won't change either. So, accepting the fact that the days and culture of 50 years ago are not coming back, do you want a guy walking around trying to find a marker, or do you want him to whip out his range finder and spend 10 seconds figuring out his yardage? Give me the second guy.
The Ford Model T is not coming back, Converse's Chuck Taylor gym shoes are not coming back, and the days of no yardage markers are not coming back. If you complain about their existance and argue for their removal, all you'll do is drive yourself nuts. Instead, let's try to figure out how to speed slow guys up given the current culture. If you can get rid of all range finders, yardage plates, and 150 markers, I'll be in your corner. But we all know that will never happen.
