I've lived hear nearly 30 yards, and the monorail was a stupid idea from the start.
The *only* way it would have or ever will make sense is if it went to the airport. The taxi companies have raised a ruckus whenever that has been suggested.
The stupid thing goes to the convention center and half a dozen participating hotels; it is nothing more than an attempt to lockin conventioneers to that set of hotels. Any expansion will just be more of the same.
Now, if you built something that went to the airport, the length of the strip, and downtown, it would be useful. But that's just not in the cards.
AFAIK, the only thing its ever done right is to escrow demolition funds when it was first built.
And now similar geniuses want to build a high speed train from Vegas to . . . Victorville. OK, other dumb ends have been proposed, but anything other than San Diego, LA, or *maybe* someplace in Orange county is back to just plain dumb. LA or San Diego without stops could actually make sense, as a 200mph run would take less time than dealing with two airports. But drive 100 miles to Victorville to catch a train to vegas??? Or take a train from vegas and, what, walk to LA
