I wave or nod most times, but the funniest is when riding with Mrs Sabie and she's on her Black Suzuki Boulevard and I'm on the STead behind her, we pass a Harley and they wave to her thinking its another Harley. By the time they pass her and see its "Jap Crap" and a woman, the disappointment is staggering, it's like they wasted a wave or were friendly to the enemy and were unfaithful to the cause or something.
I've actually seen them do the damn, foiled again look and shake their fist.....
It's funny......
