not the stadium kind mind u but just the same...not everyone does it. I find that most who do not are simply paying attention to their driving...making sure some yahoo in a Yugo or other foreign POS's dosen't go stupid on them. Last thing I would want is to trade paint with JapCrap...which makes me extra vigilant on the road in any of my Vettes'.
I even go as far and wave to any and all police and firemen...to let them know that they are appreciated...and only when I'm in one of my Vettes.
They, and this is my assumption only, tend to appreciate the 'wave' coming from Vette owners. I've been stopped and thanked for it! Pretty damn cool.
