Glow Sticks are not just for concerts.
I went to a sportsmen show last spring and at one of the booths they were giving out these Glow Sticks. Now at the time I did not think much of it as far as what to do with it but, I saved it anyway.
The one best thing I could think of is say for instance you are late leaving the woods or you are tracking a deer after dark and you get lost. You know that someone will be looking for you after awhile but you don’t want to sit out there alone in the dark and you don’t want to waste what battery life you have in your flashlight.
You can just sit and get comfortable and snap a glow stick. It will give you light so you can see and it will also light up your location for people who might be looking for you.
