It sounds like each of you made some incorrect assumptions about the other. A person who unknowingly breaks a fishing regulation is not necessarily a poacher, and may resent being labeled as such. At least I would. But his reply to you was unprofessional in the extreme. I have heard of Ron Hood although I don't know much about him. But I would hesitate to take any survival course from him if I thought that was his usual way of treating people he disagreed with. Maybe he was having a bad day, or maybe yours was not the only self-righteous email he had received on the subject. I believe Karen is his wife, so maybe he took your email as an attack on her. I'd like to hear from him as to the reason he replied that way.
