5 or 6 big bikes in my neighborhood. Most you can hear when they start them in the garage.....but my favs are the two guys who ride by on big, QUIET, adventure type bikes. Just burbling along by my window with just the mechanical noises and stock exhausts.. with those big side cases, fully geared up riders.
Riding without seeking attention is such a harmless pastime, and pleasant for the rest of us!
