There are always new things to see each time I am in Las Vegas. This is my 4th time in LV, and I am seeing this scene for the first time. I was walking along a new street next to The LINQ (formerly Imperial Palace) called The LINQ Promenade, and saw many people dancing outdoors but to what? There was no music heard from their side, until I saw the headphones on the dancers's heads and the DJ's. =) Everyone seemed lost in their own world.
