I am a practitioner of 2 years and I have experienced a similar situation where I was almost a victim of road rage. I basically told him that I don't have time for this, and that if he really wants to go at it come to my school and we will go.... needless to say he never showed up.
I met the president 2 years ago at a H.A. function in CT.He is a stand up guy, and gave me some good advice to follow.
