The 1600' hole is defined by the runway lights and if you go outside you are OB. It is roughly 90' wide which sounds generous but it is harder than you think when you are throwing as hard as you can. Most go out at least once.
Yes, 90' wide looks awfully narrow even 300' from you.
I putt for six 20'-40' out both rounds, missing both but no OB along the way.
The OB near the pin adds good risk reward to the approach as well.
