I have done a couple night runs, but I try for the full moon and prefer no headlight like Theopolis. But I always have one that is easy to get to or already in place in case things go wrong. We have ended up putting glowsticks on the back of our PFDs which are good for spotting others as w/o them it can be difficult even on a full moon. The last run we did, we put lights inside the boats to make them glow, which was fun and pretty. Kinda wish I had had someone with a camera at Pineview and a few other spots.
Definitely do a section you know since as has been said, rescues are much more difficult in the dark. But surfing in a glowing boat under a full moon is a hoot.
