I was corresponding with Michael about DIR-F in California a couple months ago. I still owe him some dates (sorry, MHK, my schedule has be rollercoastering). However, when I learned that there are several Arizona folks on the board, I hatched the idea of a DIR-F in Arizona. And now Brandon is beating me to the punch after I mentioned it to him.
There are some logistics involved with hosting a DIR-F course that we Arizona folks would have to take into account such as a classroom location, pool availability and open water facilities. And, of course, the minimum numbers of participants. I have a couple of those items tied down, but I wanted to have a defined plan before taking it to the instructors.
If you want to do a DIR-F immediately in San Diego, Tamara Kendall is running the classes almost weekly. Personally, I wanted to do mine with MHK so that I could say that I had the distinction of MHK ripping on me.
However, if there is sufficient interest in Arizona, now is as good a time as any to find out, so post if you're interested (or PM me). The course would take place in Phoenix.
