What happens in Las Vegas stays in Las Vegas. At least that's what the marketing people want us to believe. The original sin city is the fastest growing city in the US. Who would have thought that back when it was formed in 1905. It's understandable though when you consider that it is the first real adult playground featuring gambling, resorts, shopping and entertainment points of interest. Millions of tourists come to this desert oasis every year for a visit yet almost 500,000 residents call Las Vegas their permanent home. For the greater Las Vegas metro area, that number swells to over 1.5M. With no income tax and minimal taxes for most categories, it almost makes sense. Especially when you throw in gorgeous desert climate weather and enough attractions to make you head spin. Las Vegas is definitely worth a visit. Popular neighborhoods include: downtown, the strip, Henderson, Red Rock, Mesquite, North Las Vegas and Boulder City.
