That sucker (if it happens) is actually going to be
on the Strip, just south of Mandalay Bay, and across from the airport. Sounds like a traffic nightmare to me.
I literally just got back from Vegas late last night. The driver of our Hoover Dam tour was complaining about just that. He did say a lot of different locations have been/are being discussed. His take was that it would be a traffic nightmare anywhere in Vegas, basically. I can't disagree too much.
Speaking of gambling though, I played $100 on Black Jack at Caesar's Palace. Lost $92 and put the remaining $8 on Vols to win NC at 12-1.
