While the 2013 USTA League year ended on 10/27 with the completion of all of the 18 & over and 40 & over Nationals for men and women, Nationals in other divisions continue. This weekend has the Mixed 18 & over Nationals for 6.0, 8.0, and 10.0 levels taking place in Tucson.
Unfortunately, as I write this Tucson is getting one of its few days of rain a year. And in fact the forecast doesn't look great for the whole weekend. Let's hope they find a way to get the matches in.
