Island is on to something here. The best first dates involve something that gets the blood pumping, and the adrenaline flowing. Karting, Skydiving, rollercoasters, etc.. Usually, a bond is formed from sharing such "life threatening" experiences, and the odds turn in your favor. It also gives you something to talk about, and sparks conversation. I jump out of airplanes for fun, so I have first-hand accounts of this theory in action.
