From 10 July 2007, I present, the best unintentional speed bump, on The Las Vegas Strip.
The warning sign merely says:
Yeah, no kidding.
The north driveway of The Frontier, which led onto Stardust Road, was an excellent way of avoiding pedestrian traffic at the Las Vegas Boulevard exit. The dip/rise however was so significant that careless drivers entering too quickly did hit the ground instead of driving over it.
Entertainment like that just can't be planned.
