Human Factors
While descending towards San Luis Obispo; I noticed a drone pass over my left wing within 100 feet. I was descending through 2500 feet at the time; near Cal Poly University; roughly 4nm north of the San Luis airport. I only spotted the drone for a second before it disappeared past my wing and thus did not have enough time to maneuver away from it.
C172 pilot reported a NMAC with a drone while descending into SBP.
