I think others have covered this pretty well, but want to add my two cents.
I've been to the Vintage Cup and the Spring Southern several times and truly enjoyed them. Last year was my first trip to the Fall Southern. I had a blast. It is a much more intimate event than the other two larger events, and it feels that way. While there will be plenty of nice guns to look at, plenty, this event is more about the shooting.
I was also able to take part in the tower shoot last year, which was a lot of fun (I had never done that before), and I was able to go on a morning quail hunt on Sunday.
I'm coming back this year and recommend the event. Bring ammo. Go shoot.
