Phoenix is closer to Vegas, about 3:45 to 4 hours away. Tucson is about 5:20 hours to 6 hours. Depends how fast you drive.

But yeah, I would never make the PHX guys drive to Tucson, I'd probably feel bad during the event haha. But, I will note SIR is right off I10, so PHX guys wouldn't have to drive inside Tucson....

But whatever, I'll go wherever it ends up.
