The Las Vegas event is more oriented to the Mustangs. There are going to be a few Cobras there though but it's not themed around the Cobra.
I'm afraid Pomona is a little too far for me. I'll probably scope out the activities of the Ford GT group to see where they end up this year for their Rally, but it's looking like it is going to be east of the Mississippi so I'm not sure I'll do anything this coming season. Maybe try to pick up another Grand Canyon trip instead.
