2019 USTA League Nationals Dates and Locations

Update: I have learned that the resource I got the schedule from (linked in the original blog) was not accurate and the official schedule for 2019 Nationals should be published by the end of this month.  I don't know how much it will differ from what I wrote before, but stay tuned.

Update 2: As of 3/27 the schedule is out and I've written about it.   Have a look there.
