I just got one of the green lights that attaches to the bill of your cap. When I was walking out of the woods on Saturday night, I noticed a lot of shining dotsall overthe ground...hundreds of them. It sort of looked like the light was reflecting off a drop of water, but I knew there wasn't any water on the ground. I bent over to take a closer look and it was spiders! The green light reflects off their eyes like when you see a deer in the headlights. Amazing!!! I couldn't believe how many spiders are in the woods. Has anyone ever noticed that before?
