Human Factors
My goal for the day was to fly to [a nearby airport] fly-in. Weather was of major concern. Did not consult TFRs or NOTAMs. Approaching ZZZ I ran in to rain squalls and abandoned my attempt. I then flew SW around the zone of rain in the hopes of making ZZZ1 for fuel (cheapest in the region). Nearing ZZZ2; I came upon a clear path to land ZZZ1 and announced my intentions on frequency and receive an AWOS type message in response telling of wind and altimeter setting. I landed Runway 18 and taxied to fuel. While taxiing; it was noticed that an airshow had not started or was on HOLD DOWN due to recent rain. At no time during this whole incident were other aircraft flying or operating on the field. I fueled the airplane. During that time; many individuals; gas pump management; and a vehicle with yellow flashing lights drove by me and no one said a word. Once I finished fueling; I taxied to Runway 18. A pick-up truck with flashing yellow lights made no attempt to block my taxi and subsequent departure. I announce on frequency my intentions to depart and on the take-off roll a voice on frequency announce that the airport was closed. I continued my take roll and once airborne (<1000 feet from threshold) made an immediate downwind departure away from the air show general area. At no time; except for fueling; was I within 3/8 mile of spectators.
Scout pilot reported arriving and departing a fuel stop airfield unaware that the airport was closed.
