A while ago there was talk and a website for the "X-Train": a train that was going to travel from L.A. to LV. It was to have a Las Vegas party theme and was supposed to begin its run on New Year's Eve. Any news or updates, or was it just a big hoax?

Is there a bicycle lane on the Las Vegas Strip?

In the D Concourse in Las Vegas McCarran Airport, there were some really cool sculptures that appeared to come out of the floor, like a scorpion. When I flew in the week of Nov. 16, 2009, they were gone. What happened to them? Can we see them somewhere else?

What are the top employers (in terms of people employed) in the casino industry in Las Vegas?

I have a mobility scooter and I’m wondering are the pedestrian bridges over the strip accessible? And if so how?

Star Trek: The Experience -- what are the plans to relocate this? There's nothing going on at Neonopolis and I heard a rumor the other day that it will appear at the new CityCenter.

I've noticed that the Green Valley Ranch shuttle was removed from your list of shuttle services and was wondering why it was eliminated? Were there not enough passengers using this shuttle to make it profitable?

While watching "Pawn Stars" tonight I saw a Las Vegas open-top sightseeing bus. Are they crowded? I wouldn't want to ride it if I couldn't be on top.

I would like to take a helicoptor tour when I visit in April. Are these companies regulated by the state and can you view safety and maintenance records somewhere?

There has been a lot written about room rates in Las Vegas. However, little attention has been paid to car-rental prices, which seem way up to me in Las Vegas and most everywhere else. Adjusting auto-rental fleets is a lot easier than adjusting room numbers. I don't have solid stats, but I'd almost take an even bet that much of the savings due to the hotel glut for John Q. Tourist has been eaten up by auto-rental prices and fees. What say the experts?
