Narrative:

I was flying a peninsula tour to crystal springs reservoir; and then proceeding south to stanford stadium via the santa cruz mountains (west of sql) with two passengers. Prior to the flight; I had checked sky vector for any active tfrs as I usually do. There was a game that day at stanford stadium; which I thought had ended; as it no longer showed up in a sky vector; and it was past the proposed end time. Typically; when there is a tfr over stanford stadium we will stay at least 3 NM from the stadium and above 3;000 MSL; or we will take a different route entirely. However; this time I did not because to my knowledge the tfr was no longer active. As I was approaching the stadium at 2400 feet (well above palo alto's; pao; airspace) I noticed that the stadium was still about half full of people. At that point I attempted to make a turn towards the south to try and put as much distance from my aircraft and the stadium as possible. I then contacted san carlos tower for a clearance to approach and land on runway 30. It was after I landed that I was informed by san carlos that palo alto tower wished for me to call a phone number in response to a possible pilot deviation. From what I have learned; the game may have gone into overtime or was in some other way extended; thereby rendering the tfr still active. Through my typical means of checking tfrs; I was unable to discover this prior to the flight.
