I have only had a few choice comments tossed my way. The one I remember most was one rather large lady (i'm from UK, living in Texas, slowly reducing my plus size person!) in a car shouting that I should get off the road. I suggested she get off the couch more often. It was one of those impulse responses that didn't go down well.
Now I just smile and wave. Although this past couple of weeks there has been an awful lot of smiling and waving. I think it's been getting hotter and peoples tempers have been getting worse.
Oh, something this thread just reminded me of. My parents and both brothers were here visiting recently. We all ride. My parents, both in their mid-seventies, just left Sunday. When any combination of us are going somewhere in a car the first to see someone on a bicycle will always spout off, "Damn bicyclists!"
In this group this is very funny.
Any kind of animal in the road always gets a, "Git out'ta the road ya' hippie!"
