With my hunting spot in CO I try not to use any lights at all unless I need to, but it is also about 10 minutes from where I park to where I start to hunt (I like to go after the game other people overlook and walk right past).
Sounds similar to me. If there is any moon, I usually can start walking in about a half hour before legal shooting time. If there is a full moon, I could walk in anytime. I can't remember the last time I turned on a light walking in, once I am off a road. No snakes or grizzlies in my area.
