Lately the winds around here have been about 25mph with gusts of 30mph. Riding against the wind sucks, but when I turn around...WOOHOO!
Had a couple of experiences while riding into the gale where a car came up behind me ("out of nowhere") and I couldn't hear anything do to the roar of the wind. I ride fairly low travelled rural roads out among the cornfields, so when a car comes up on me it is usually travelling at a high speed. Disconcerting when I check my mirror and read FORD!
Anyone ever use some sort of ear plug? I know way back someone made Mickey Mouse ears looking things you attached to your helmet straps that basically deflected the airflow over and past your ears. Rather funny looking, but effective I suppose.
