I'm not aware of any formal event in Arizona. There are several of us in Arizona, mind you. Just no one brave enough to host an event in their home, or arrange a munch in a local restaurant, yet.
There are several from Arizona on the West Coast Gatherings mailing list. Met a few of them. Good folks.
In addition to the West Coast Gatherings, there's also other events you may wish to attend. The Texas Gathering is about as long a flight as the West Coast Gatherings, as are the flights to the Southern Gatherings in Memphis. Of course, there's ALWAYS good reason for the longer travel to NEST.
Also, if you're planning a holiday, do consider targeting an area that has an event. I've done so many times, and it's always a better holiday!
