Now that road-safety laws have tightened up since the '70s when Fear and Loathing was published, you'll need to look at alternative transport for your LA-to-Las-Vegas trip if you want to play Hunter S. Thompson while under the influence.
A gambling train? Sure, I think Thompson would improve. There are no bats on trains, after all.
Believe it or not, the X Train is actually going to happen, with the developers boasting of a 2011 launch. It'll use converted railcars, and as the renders show it'll be very red! plush! swirly-swirly! plush! Though apparently one of the photos—this one—is actually a real-life photo from the Blue Train, in South Africa. Puzzling.
