Indeed. Vegas is about as sanitary and clean as it gets. There's almost no sleaze left. Fremont at night can get sketchy, but only in the sense of desperate poor people.

But I guess that's how good they are at selling the myth of Vegas. They want you to believe it's wild, sexy, out of control, and naughty. In reality, it's all highly regulated, calculated, and completely under control by large corporations.

That depends a lot on your definition of sleazy and sanitary.
