Course Rating is 68.8 at this course, so it's not is a super difficult course for a pro. It's pretty short, too. 6100 yards is on the short end, even for a muni. Bubba's differential was -6.2, if the online calculator I used is right. Interesting to see.
I just checked my USGA GHIN app and they notified me of a new GPS feature. It looks interesting. I will check it out next time I play. Here are the notification screen shots. My name is not John Doe BTW.
