Las Vegas Wild West setting on CSI?

Try:

Bonnie Springs:

The Wild West is still as wild as ever in Old Nevada, a replica of an 1880's mining town built on the 115-acre Bonnie Springs Ranch.

Las Vegas is the epitome of the fast-paced, ultra-modern city - swank, glittering, and exciting; but just a short, 30-minute drive away, you can visit the past again. Bonnie Springs Old Nevada is John Wayne country. Boarded sidewalks that creak pleasantly under your feet, saloons, tumbleweeds, stagecoaches, and even a Boot Hill Cemetery.

Bonnie Springs Old Nevada is a great place for the family and there are tons of attractions for the kids. There is a petting zoo, cowboys and cowgirls, a miniature train ride, and on weekends and holidays, a "posse" show where the kids can even help track down the 'bad guy". This little old mining town offers plenty of rousing, rough-and-tumble action, simulated gunfights in the streets, an 1830's melodrama complete with mustachioed villian in its authentically recreated Saloon, and even a public hanging, with an obliging Stuntman swaying in the wind.

In addition to our gunfights and cowboys, there's a wax museum with figures from our frontier history, great homemade meals at our restaurant, a beautiful 1800's style chapel which is great for weddings, conventions facilities, and plenty of shopping for those looking for turquoise and silver and other western souvenirs. Bonnie Springs Old Nevada is an adventurous outing for the whole family and we're open every day of the year!

It is the only thing I could find anywhere close to it on the Las Vegas Visitors Site
