Ya know, that is funny. I took a motorcycle trip from Monterey CA to Fairbanks AK in 1976. I was never waved at until I was in Canada. Times have changed, Harley owners will now talk to Honda owners. But do RVers wave? I don't see that much. We wave. Maybe because we too are new at it or maybe because it's fun to see the looks on thier faces as they seem to be thinking "Do we know then?". If we see a TANGO trailer, for sure. We have a TANGO and don't see many. Go ahead, WAVE, SMILE
and drive them nuts! I have met some great people once you meet them one on one.
