My dream round that I have yet to achieve in about 40 years of playing this game is 18 pars in a round. I am a true believer that course management is probably the single biggest factor in keeping the big numbers off the card. Risk / reward should be considered on just about every shot that is played during a round. Sometimes hitting to the center of the green to set up an easy two putt par is preferential over taking a chance and shooting at a tight pin where a slight miss brings bogey or even double into play.
I am on a current streak of 75 straight rounds of making at least 1 birdie during each round. My longest streak is 87 rounds. I would gladly break the streak or trade both of those long streaks for just one bogey-free round.
