Pictured above is a graphic representation of the Las Vegas Strip in 1930 when the only casino was the Pair-o-Dice Club. The Strip wasn't the Strip then, it was just Highway 91.

The below picture is the Strip in 2007, and even that's already outdated with the implosion of The New Frontier where Pair-o-Dice used to be.

The very fun interactive map can be found at Las Vegas Sun.

You can see timelines from 1930, with decade and half-decade marks. Each 3D casino has popups giving brief facts including openings and closings.

The map gives a good overview of all casinos on the Strip, downtown, and in the Valley. Also included are timelines, slideshows, lots of links, biographies of entertainers, and more.

It's our first go-to guide when looking up the history of a casino or if we just want to find out what's now in, say, Silver Slipper's old location (answer: nothing yet).

Cross populate it with Google Earth and heck, you'll feel like you're right there.

Jeez, what would we do without the Internet?
