What to do, when you see a fellow Z owner?

Vince's Red-Z

Have you ever seen bikers wave at another? Truckers lift their hand at another trucker? Bus drivers nod at another? What do you do, when you see fellow Z owner? Let's make a senses of this:

1. Flash high beams
2. Roll the drivers window half way down, to see who is driving
3. Turn on parking lights
4. Make right signal light blink twice
5. Put in natural and rev your engine
6. Put you hand in the air

From reading the replies, I plan on rolling my window down (or make sure its seen) and giving a thumbs up.
