I know, I know, this is a stupid question but...Do you give the "biker wave" to scooters? I usually do because sometimes I don't even know there're scooters (some are pretty big) until they pass. So, I wave--but I NEVER get a wave back!! Hmmm-social class thing (they're better than us) or are they just not use to it. PS--If this is all I'm thinking 'bout, guess I need to get a life!!! LOL
