I did that over 7 years ago and your the first that I know of.
John, for a short while they had those long, narrow advertisement trucks going up and down the Vegas strip, each truck had three brass poles and live performing pole dancers in them. They created enough traffic problems/accidents they no longer have them!! They were here for a couple months. Loved them!!! Never did take a photo of them though. It seems I was always the driver when we got next to them.
Love this town!!!
