OK. We're trippin on the beach at night. We got some of those glow sticks you bend and shake. Throw those in the ocean, watch the cool green glow. Jump in and swim around, retrieve sticks. Repeat several times. Fun. Watch the green glow in the water with little fishes swimming around. Cool. Light attracts little fish.... attract big fish..... attracts sharks because this is the ocean. Not cool. Hair stands up on back of neck, serious heeby-jeebies. Run back to hotel for beer, smoke, tunes. Takes awhile to shake those chills. Never saw anything bigger than a minnow in the water, but the big sharks were certainly just outside the glow waiting on a clumsy trippin seal for dinner.
