This is a piggyback off of a lower thread...Didn't want to hijack it.

What is the propper form of the motorcyle wave? In my short riding career I've seen several variations. From the palm up/lame 'Hi guys!!!' regular wave to the serious two-finger down-could-be-mistaken-as-a-left-turn-hand-signal. Which do you use? I've heard the two fingers down means to 'keep two wheels down'... I guess vs. up, which is nice...kind of like a well wishing...
