The last they held directly was May 13-15 2022 in Munford, Alabama.
For 2023, there was no separate National Convention, as the "SR20 Reunion" in California was the only event.
It was intended combine National and West Coast conventions, but since it was in California, most of the National Convention folks didn't make the trip.
There were a handful of people who flew out including myself, Christ Parker, Cameron McFarlin, but the furthest road trip in was from Texas.
The 2024 West Coast Convention was announced in January for October 18th-20th in Bakersfield, CA with a track day at Buttonwillow through Speed Ventures and Nissan Challenge.
There has been no teasing of any other convention for the 2024 calendar year, and since the National Conventions generally happened in the late spring, I'm assuming no announcement is coming for a National Convention.
