I am the youngest of our marshal/starter group , only one under 60, there are two between 60 and 65 then the remaining 12 or so between 65 and 74. We always play the white tees which is the 4th deck from the back. It plays a long 6280. There are only 2 holes that about 2/3 cant reach in regulation, the par 4 8th at 410yards and the the 18th at 408. All 5 par fives are over 500 from the whites and max out at 545 and no issues.
our ladies tees are 5530 yards and most of the juniors under 15 play that along with the ladies. A few 80+ year old members also will use a white/red combo
