Yes Vegas is Pacific Time....
CosmicArkie did get a chance to say hello to Bobby on his way out of the hotel and even got a hand shake... how sweet
I remember the question of the time zone coming up last year. And Vegas seems to be the latest start on the tour.
So, yeah. 11:00pm start, for us east coasters. Probably go til around 3. (And I checked, no mention of a sirius stream)
