I'm so excited to see such a great response to this! As for dates, I'm probably not the best one to comment. I'm wide open the entire week of the 6th, with the exception of the 6th itself. Those with busier schedules should probably weigh in

If we stick with the East Valley, there are tons of options for venues, lots of great restaurants. I've lived here almost 2 years now but I still don't know the "best" places to go. I'm up for anything and willing to drive to wherever the group would prefer to meet (and pick up OSAAT).
Linda, Chandler and Gilbert are in the East Valley, so we should all be nearby when you visit. I think the East Valley stretches to the ASU area, too. Again, I'm newer to the area so I could be wrong on that, but ASU is in Tempe and that's not far from Gilbert or Chandler.
