It's Thursday. You just had the night of your life in beautiful Las Vegas, Nevada. You spent hours shooting craps, dancing in clubs, and eating more than your fill at the famous All You Can Eat Buffets.

You're staggering back to your hotel room, high on life, in the early hours of the morning when you notice something strange: A long, dark tunnel on the edge of the strip. You didn't notice it on the way in, perhaps because you were distracted by all the gliz, glamor, and hypnotic casino lights.

Seeing an opportunity to escape the overstimulation of Vegas, you enter the tunnel.
