I think that most riders here in West Virginia always wave. I mostly see Harleys and Goldwings on the road and the most common wave is the arm toward the ground at about 45 degrees and the thumb and two fingers extended. I ride a lot across the river in Ohio and most of the "Buckeyes" return or initiate the wave. I'll be glad when riding weather returns......that first warm day always brings out the bikes, smiles and LOTS of waves!!!
