So, I am riding to school and I notice that most oncoming bikers are waving to me now, even hogs. They are giving me the low left hand wave almost like they are signaling left. Ive heard that this the the "wave of choice", but not too familiar with it. I am asuuming that the return wave is the same thing, but I dont know for sure. I dont want to be the ass that doesnt wave or wave back. So what do you guys usually do?
