The best way to get in touch with Shannon is Email and it makes sense. If he is on the range shooting he can’t hear the phone ring. If he is teaching in the classroom, it would be rude to his students to answer the phone during class. If he is driving, or otherwise occupied, it could be dangerous to answer the phone. He will answer the phone if he can, but the course, schedule and registration information is here on the website. And some really embarrassing lapses of memory, etc., have occurred when he has tried to answer the phone while driving the tractor.
Please, Email Shannon!
