Amergin... do you get those looks, too ? I used to be shy about it, even in my truck with the windows rolled up. Nowadays, I have taken to enjoying the variety of looks I get. When I get the really odd or concerned looks, I give em a nod or shrug my shoulders and smile. I guess some people just can't believe one can be happy (rude ? (of course, I don't sing loudly)) enough to whistle or sing in public.
