Ok, it isn't really the last, as there are some mixed and perhaps other leagues that have their Nationals in November, but for the 18 & over and 40 & over leagues, this is the last weekend of Nationals in what has been an October (and bit of September) packed with play. With the introduction of the 40 & over league this year, there was a bunch more play.
In Tucson this weekend is the 18 & over 3.5 Nationals. I have a team I've helped with reports playing there so will be following it closely.
Then in Indian Wells is the 40 & over 4.5+ Nationals. I also have a team I've helped playing there so will follow as well.
Stay tuned for updates as I'll likely take a look at how my ratings do prediction matches.
