UPDATE! Holes 5,6,7&8 are in and playable! 5 plays off the field on the edge of the woods up behind 2. It is really long and tough. Probably going to be a legitimate par 4. 6 plays out over the the edge of the pond back out into the field. 7 (island hole) plays right back over the pond at about 375. 8 is a lot like 5 but even longer with a more narrow fairway through the woods back towards 2. It is another legitimate par 4.
Overall, the new holes really take this course to another level of difficulty and variety and are going to make it a must play in the OKC metro area. It has been great the couple of times I have helped out for work days to see it's development first-hand.
