You've probably guessed this course is special to me. I lived in Northern Virginia after retiring from the Marine Corps. I attended Warrant Officer Screening Course and Warrant Officer Basic School at Quantico in 1973. Frankly, I've only played this course twice, it's a nice IRL course.
The map will give you an indication of why everything runs to Fuller Road... which is the main road from the gate to mainside. Fuller Road runs through the valley parallel to Little Creek. So everything flows to the creek. Front nine to the left and back nine to the right of the clubhouse.
I like that there are several blind tee shots... more a concert IRL than in Links where the Top Cam is available.
Enjoy. The start of the wrap around season begins next week with the Fortinet.
