My favorite attraction in Los Vegas after the Polaroid Museum was old Los Vegas, or to be exact was the Container Park. The main strip in Los Vegas had almost no appeal to me but as we rode the bus north I started seeing graffiti and immediately started feeling more at ease.
Some authenticity at last.
At any rate, I don't know this for fact but heard it from locals, Tony Hsieh the CEO of zappos has bought up huge tracks of old downtown Vegas and has been sprucing it up. There is some cool stuff happening there. But like all change, not everyone is happy. Businesses that have been there forever, like tattoo shops have been banished and not surprisingly aren't happy with the changes. Reminds me of the hand wringing when NYC cleaned up Times Square.
But the Container Park is pretty amazing, with the exact same methodology of parks in Cincinnati. family friendly with special events happening all day long for entertainment.
