Narrative:

Reporter was in cruise flight, level 8500 ft MSL, VFR direct from ccr to chester, ca (O05) on radar following with ZOA. Had been vectored away from beale AFB for airshow activities. Approximately 10 mins later, ZOA called to request how we heard center. We responded 'loud and clear.' then ZOA advised we had penetrated a fire fighting restr area set up on the 060 degree radial, chico VOR, 30 NM, 13 NM radius. We established position and advised ZOA of left turn to clear the restr area, which we did at once. Requested radar vectors to O05 clear of the restr area. Vector received and flight was completed without other event. No conflicts or other aircraft observed or heard on ZOA frequency. We were unaware of the restr in the area and entered it unintentionally. This could have been avoided by my obtaining a preflight briefing (which I did not because of VFR conditions and familiarity with the route) or timely advice from ZOA.

Title: PVT PLT OF BEECH BE35 BONANZA INADVERTENTLY PENETRATED TEMPORARY RESTR AIRSPACE DUE TO NOT KNOWING THE AREA HAD BEEN DESIGNATED BECAUSE OF A FOREST FIRE.

Narrative: RPTR WAS IN CRUISE FLT, LEVEL 8500 FT MSL, VFR DIRECT FROM CCR TO CHESTER, CA (O05) ON RADAR FOLLOWING WITH ZOA. HAD BEEN VECTORED AWAY FROM BEALE AFB FOR AIRSHOW ACTIVITIES. APPROX 10 MINS LATER, ZOA CALLED TO REQUEST HOW WE HEARD CTR. WE RESPONDED 'LOUD AND CLR.' THEN ZOA ADVISED WE HAD PENETRATED A FIRE FIGHTING RESTR AREA SET UP ON THE 060 DEG RADIAL, CHICO VOR, 30 NM, 13 NM RADIUS. WE ESTABLISHED POS AND ADVISED ZOA OF L TURN TO CLR THE RESTR AREA, WHICH WE DID AT ONCE. REQUESTED RADAR VECTORS TO O05 CLR OF THE RESTR AREA. VECTOR RECEIVED AND FLT WAS COMPLETED WITHOUT OTHER EVENT. NO CONFLICTS OR OTHER ACFT OBSERVED OR HEARD ON ZOA FREQ. WE WERE UNAWARE OF THE RESTR IN THE AREA AND ENTERED IT UNINTENTIONALLY. THIS COULD HAVE BEEN AVOIDED BY MY OBTAINING A PREFLT BRIEFING (WHICH I DID NOT BECAUSE OF VFR CONDITIONS AND FAMILIARITY WITH THE RTE) OR TIMELY ADVICE FROM ZOA.
