Narrative:

On direct flight from hio to the coast at 4;500 ft MSL; my grandson in left front seat was setting up to take pictures w/his iphone while my wife was right hand rear passenger. While westbound over pacific coast range; approximately half way between hio and the coast; my grandson exclaimed; 'wow; that was close.' having seen nothing; I asked what he saw; after landing; I questioned both passengers about what they observed. Left front passenger stated he saw a blue single engine aircraft descend from above; right to left; just missing our left wing. Right rear passenger reported only a flash from right to left. I neither saw nor felt anything. I was monitoring 122.9 at the time. My aircraft has no autopilot. I was maintaining heading and altitude with no weather obstructions.
