C182 TRANSITIONING THE LAX AREA IS CONCERNED ABOUT POSSIBLE PENETRATION OF TFR.

Narrative

I WAS TAKING A COUPLE OF FRIENDS FOR A FLT TO SMO FOR LUNCH. WE DECIDED TO AVOID THE SFR AREA AND THE ROUTES REQUIRING A CLRNC OVER LAX BY HEADING E AND EXPLORED THE LA DOWNTOWN BY FLYING UNDER THE CLASS B. WE RECEIVED A CLRNC TO GO THROUGH THE LGB CTL AREA OVER THE LA RIVER BASIN AT 1800 FT MSL. ONCE CLR OF LGB'S AIRSPACE; WE PROCEEDED TOWARDS DOWNTOWN WITH AN INTENT TO TURN W AFTER CLRING THE DOWNTOWN AREA. AS I ESTABLISHED CONTACT WITH SMO TWR AND RECEIVED CLRNC TO LAND; I NOTICED THAT THE DODGER STADIUM; WHICH WAS APPROX 2-3 MI AHEAD; TO THE R OF ME; HAD CARS AROUND IT AND THE JUMBOTRON WAS WORKING. I INSTANTLY TURNED AWAY FROM THE STADIUM WHILE CONTINUING TO THE W AND PROBABLY PASSED CLOSE TO WITHIN THE 3 MI RADIUS IF A TFR WAS PRESENT. I AM NOT SURE IF A TFR WAS PRESENT. SMO TWR ASKED ME TO IDENT AND MY LOCATION. I RPTED DOWNTOWN LA AND IDENTED. SMO TWR THEN CLRED ME TO LAND; AND DID NOT MENTION ANY TFR. WHEN I HAD CALLED THE FLT BRIEFER EARLIER IN THE DAY; HE DID NOT MENTION ANY TFR'S OVER THE LA AREA. SO; WHILE I AM NOT SURE IF THERE WAS A TFR OVER THE AREA; I WILL BE SURE TO AVOID ANY STADIUMS AS A MATTER OF COURSE AND WILL BE SURE TO DOUBLE-CHK IF THERE ARE ANY TFR'S ENRTE.
