Sounds like Sunday night would be best... that means we'll leave around midnight in CA, and arrive back in AZ in the early morning.
As for leaving, I have to go home, pack, get some sleep, and I suppose I'll wake up around 1 PM. We can leave around 1:45 PM to 2 PM, just make sure you're here before 1:30 PM, H-F. Space shouldn't be so much of a problem this time, I think.
My number is still 480-570-4381 if you need it.
