theres regional meets all the time,just check the regional forums for them, and theres only about 3 big meets a year..... Chicago, Las Vegas, and Texas.
I have been working on expanding the PacNW Supras calendar to allow anyone to add events for anywhere in the world. I'll have to get back on that. My plan is that the list would be sortable by region and or event type. It is nearly done... If we want this I could easily do it and host it at www.Supras.org.
