Narrative:

After a normal landing at O01, was notified by an employee of a movie production company that the airfield was closed (temporarily) for the filming of a movie. Further he said that NOTAMS had been issued and the runways X'd out. After some discussion I departed VFR with the permission of the movie company. Before making this flight I had received a standard briefing from rancho murieta FSS. I gave the route of flight as 'auburn direct santa rosa' but do not recall specifying which airport in santa rosa (there are 2). In any case there were no NOTAMS given to me regarding closure of this airport during the briefing. During the flight, which was VFR, I had radar flight following from sacramento approach and also oakland center until I reported the (santa rosa) air center in sight. Runway 16 (which was active) at santa rosa air center has a displaced threshold. Upon takeoff I noted that the 'X' was indeed painted on the runway, but was back in the inactive area on the runway, which is one reason I didn't notice it. Other items of note. There were ground vehicles on the taxiway when I landed, but the runway was clear. The person who stopped me had a handheld transceiver, but never contacted me before I landed. I had announced my approach on the unicom frequency 122.8 on '45 approach for runway 16, 3 mi out', '45 for 16, 1 mi out', 'left downwind for 16', 'base for 16', and 'final for 16'. There was no communication from ground personnel during my approach. Things to be learned: never take for granted the conditions at a field you have flown into frequently. I routinely fly into and out of this airport several times a month, although I am not based there. Suggestions: clearer dissemination of NOTAMS if in fact they were in the system. If the airport was being used unicom should have been monitored and aircraft warned before landing, especially since this is not a permanent closure.

Title: GA SMA LANDED ON A CLOSED ARPT.

Narrative: AFTER A NORMAL LNDG AT O01, WAS NOTIFIED BY AN EMPLOYEE OF A MOVIE PRODUCTION COMPANY THAT THE AIRFIELD WAS CLOSED (TEMPORARILY) FOR THE FILMING OF A MOVIE. FURTHER HE SAID THAT NOTAMS HAD BEEN ISSUED AND THE RWYS X'D OUT. AFTER SOME DISCUSSION I DEPARTED VFR WITH THE PERMISSION OF THE MOVIE COMPANY. BEFORE MAKING THIS FLT I HAD RECEIVED A STANDARD BRIEFING FROM RANCHO MURIETA FSS. I GAVE THE RTE OF FLT AS 'AUBURN DIRECT SANTA ROSA' BUT DO NOT RECALL SPECIFYING WHICH ARPT IN SANTA ROSA (THERE ARE 2). IN ANY CASE THERE WERE NO NOTAMS GIVEN TO ME REGARDING CLOSURE OF THIS ARPT DURING THE BRIEFING. DURING THE FLT, WHICH WAS VFR, I HAD RADAR FLT FOLLOWING FROM SACRAMENTO APCH AND ALSO OAKLAND CENTER UNTIL I RPTED THE (SANTA ROSA) AIR CENTER IN SIGHT. RWY 16 (WHICH WAS ACTIVE) AT SANTA ROSA AIR CENTER HAS A DISPLACED THRESHOLD. UPON TKOF I NOTED THAT THE 'X' WAS INDEED PAINTED ON THE RWY, BUT WAS BACK IN THE INACTIVE AREA ON THE RWY, WHICH IS ONE REASON I DIDN'T NOTICE IT. OTHER ITEMS OF NOTE. THERE WERE GND VEHICLES ON THE TAXIWAY WHEN I LANDED, BUT THE RWY WAS CLR. THE PERSON WHO STOPPED ME HAD A HANDHELD TRANSCEIVER, BUT NEVER CONTACTED ME BEFORE I LANDED. I HAD ANNOUNCED MY APCH ON THE UNICOM FREQ 122.8 ON '45 APCH FOR RWY 16, 3 MI OUT', '45 FOR 16, 1 MI OUT', 'L DOWNWIND FOR 16', 'BASE FOR 16', AND 'FINAL FOR 16'. THERE WAS NO COM FROM GND PERSONNEL DURING MY APCH. THINGS TO BE LEARNED: NEVER TAKE FOR GRANTED THE CONDITIONS AT A FIELD YOU HAVE FLOWN INTO FREQUENTLY. I ROUTINELY FLY INTO AND OUT OF THIS ARPT SEVERAL TIMES A MONTH, ALTHOUGH I AM NOT BASED THERE. SUGGESTIONS: CLEARER DISSEMINATION OF NOTAMS IF IN FACT THEY WERE IN THE SYSTEM. IF THE ARPT WAS BEING USED UNICOM SHOULD HAVE BEEN MONITORED AND ACFT WARNED BEFORE LNDG, ESPECIALLY SINCE THIS IS NOT A PERMANENT CLOSURE.
