I am no birdie machine but every once in a while several in a row go in. My best string of holes goes back years: eagle, birdie, birdie, birdie. At the time I had never shot under 45 for 9 holes and never broke 90 for a full 18. For that brief period of time I was unstoppable. After opening the round with a double bogey I rolled in a putt for my first eagle and then followed that with 3 consecutive birdies. Thoughts of a course record were quickly extinguished by a series of bogeys, doubles and triples. Barely kept it under 50 for the nine.
Since that time the best I have been able to do is three consecutive birdies and those occurrences are few and far between. Don't really know what my best string of "par or better" holes is. I know I have never made par on every hole for nine.
What about everyone else?
