One thing I've learned over the years.....

If you don't use a headlamp....our eyes adjust "pretty well" to the low light....especially with any appreciable moonlight available.

I find that, although I have a light with me....I RARELY use it...not even to get my climber ready. My haul line lets me know how far up the tree I am. If I don't have a pre-set spot to get to in the tree (rare).....then I know when I reach a certain height (run out of haul line).

I go out many times without a light....and I go early.
