I've rarely known anyone who knew about the spider-finding power of flashlights before. Long ago a friend told me and I told some friends and we'd get together to walk around at night spiderhunting by holding flashlights to our foreheads. If you walk around like that and look into the center of the beam you can always find spiders. It's very creepy, because you'd see this little glowing spot in the weeds by the house, and then you'd move in on it very slowly, staring into the light, and you'd get to where all you could see was this growing orb of light, fluctuating on the weeds with this little spark in the middle that would get larger and larger as you approached until AAARGH there was a huge spider looking back at you. We were usually pretty buzzed when we did this.

I just got here. Could someone summarize for me?
