Congratulations -- year is still young and plenty of season yet to play so I am sure you will beat that.
Wow great round Fred!! 10 birdies is pretty awesome. My best birdie round is a 6 birdie round where I started poorly but caught a hot putter late and managed a "way to high" 74. (For 6 birdies that is.) My best round is still a 69 I shot in 2006 with 3 birdies on front and 2 bogeys on back for a -1 round of 69. The closest I've ever been to a clean no bogey scorecard.
You guys all make me jealous :) My best round isn't even in the 80s! (yet).
Thats why I love this game though. Tons of room for improvement and I can see it happening! Just need to turn that corner. Great rounds folks. Keep em goin!
