I almost comitted the ultimate in rider waving taboo last night. I was crusing home, enjoy some nice side streets when I see the head lamp of another biker coming my way. I have a little formula for waving now: Another crotch rocket, I have the wave ready to go; a street cruiser and I'm in stand-by mood; a harley and I barely make eye contact, let alone prepare to even return a wave let alone start one.
So anyway, from a distance I see what appears to be another rocket coming my way, so I'm getting ready to slid the low wave off to him. Just as my left hand was about to leave the grip, I noticed I almost waved to A SCOOTER!!!!!! What was I thinking? Thankfully I corrected myself and was able to save the embarassement I would have endured at such a mistake.
