I’ve ridden enough to remember the days when seeing 2-3 motorcycles on tour was the norm. My first tour I recall see two BMWs in Montana with Canadian plates, not one US licensed bike in over 3,000 miles. These days, bikes are much more prevalent and most do wave. I do see clique riders though who tend to only wave to similar bikes, Harleys to Harleys, Goldwings to Goldwings, BMWs to…but most still wave regardless. And looking around is fine, it’s why I ride, to see the scenery. Like I said though, looking too long on curvy mountain roads can be very tricky. I almost never see any touring Hayabusas. Have you seen many?
