Mafia Wars: 3x job mastery in Las Vegas

Well, now we know what the Magnum Shotgun was added for! Of greater interest than the Magnum Shotgun, though, is the 3x mastery being offered in Las Vegas now through next Tuesday, December 6th. Of course, they waited til I was almost done with Vegas to offer this :D Oh well, I'll take it. This should make Vegas a quick finish for me now. I like these extra mastery events.
