Haha... Yes lights... lots and lots of lights. Most ski areas offer night skiing and they light up the mountain. Something about the nighttime air though that gives me a thrill... that, and looking up and seeing stars... REAL ones, not the ones you see when you wipeout
Only thing is, it's usually 15 degrees colder at night so you really feel it.
I imagine snowboarding adds the same extra exhiliration at night, though I haven't tried it... maybe I will THIS winter.
