Narrative:

While flying to wvi and still talking to norcal after exiting sfo class B; a silver drone passed about 50 feet left of my plane and about 100 feet below. I was at 4;500 feet on a heading of about 140. I reported the incident to the norcal controller who then asked a series of questions with lots of interruptions to talk to other traffic. He was still getting information from me when I entered the pattern at wvi. There was considerable traffic at wvi including parachute jumpers and a meridian with minimum fuel. I didn't switch to the wvi unicom until after I had entered a right downwind for runway 20 because I was still providing drone information to the controller. I mistakenly entered a right downwind instead of a standard left downwind pattern. It didn't create any conflicts; but was not correct. I should have stayed at cruising altitude and completed my involvement with the controller before entering the pattern. I allowed myself to be very distracted and was way behind the plane. The illegal drone and near miss was the primary contributing factor. There has to be a way to control the drone operators.
