see a lot of motorcyclists on the natchez trace parkway
never had a real problem ....
the "crotch rockets" seem to appeal to younger and often more reckless riders... they can cut it a bit close at times AND i cant hear them if there is any significant wind noise ... making for an unpleasent suprise as they zip by at 70mph
honda gold wings are ideal...loud enough to hear but not as deafening as a harley...both seem to be ridden by more mature riders . they will often wave
