Narrative:

I was flying to ZZZ, us, from ZZZ1, us, part 91. I was ahead of schedule and decided en route to alter course to ZZZ3, us, to buy some fuel (50-60 cents cheaper). I completely forgot about the possibility of a tfr around the closed X power plant. I had not initially planned on stopping at ZZZ3 airport so I didn't review airspace restr along that flight plan. I also did not see the plant (fog-low clouds in its vicinity) which hopefully would have alerted me to check its status. I have received numerous FSS briefings on tfr's and have marked all pertinent ones on my charts. I made several radio calls as I approached the airport indicating my position and intentions. As I entered the pattern the unicom stated that I had flown through the tfr per phone call from TRACON. I initially thought that since the plant had been closed for some time that there was no tfr. I reread the NOTAMS when I returned home to verify if it had been added to the tfr list. I did not find it initially. I did not realize it was across the river on the ZZZ2, state side and was listed under there, instead of xx, state. In retrospect, I now realize a broader area of airspace review is necessary on longer cross country flts when flying close to borders and other possible deviations from the planned route of flight that may arise.

Title: AN INADVERTENT ENTRY INTO A TEMPORARY FLT RESTR AREA.

Narrative: I WAS FLYING TO ZZZ, US, FROM ZZZ1, US, PART 91. I WAS AHEAD OF SCHEDULE AND DECIDED ENRTE TO ALTER COURSE TO ZZZ3, US, TO BUY SOME FUEL (50-60 CENTS CHEAPER). I COMPLETELY FORGOT ABOUT THE POSSIBILITY OF A TFR AROUND THE CLOSED X POWER PLANT. I HAD NOT INITIALLY PLANNED ON STOPPING AT ZZZ3 ARPT SO I DIDN'T REVIEW AIRSPACE RESTR ALONG THAT FLT PLAN. I ALSO DID NOT SEE THE PLANT (FOG-LOW CLOUDS IN ITS VICINITY) WHICH HOPEFULLY WOULD HAVE ALERTED ME TO CHK ITS STATUS. I HAVE RECEIVED NUMEROUS FSS BRIEFINGS ON TFR'S AND HAVE MARKED ALL PERTINENT ONES ON MY CHARTS. I MADE SEVERAL RADIO CALLS AS I APCHED THE ARPT INDICATING MY POS AND INTENTIONS. AS I ENTERED THE PATTERN THE UNICOM STATED THAT I HAD FLOWN THROUGH THE TFR PER PHONE CALL FROM TRACON. I INITIALLY THOUGHT THAT SINCE THE PLANT HAD BEEN CLOSED FOR SOME TIME THAT THERE WAS NO TFR. I REREAD THE NOTAMS WHEN I RETURNED HOME TO VERIFY IF IT HAD BEEN ADDED TO THE TFR LIST. I DID NOT FIND IT INITIALLY. I DID NOT REALIZE IT WAS ACROSS THE RIVER ON THE ZZZ2, STATE SIDE AND WAS LISTED UNDER THERE, INSTEAD OF XX, STATE. IN RETROSPECT, I NOW REALIZE A BROADER AREA OF AIRSPACE REVIEW IS NECESSARY ON LONGER XCOUNTRY FLTS WHEN FLYING CLOSE TO BORDERS AND OTHER POSSIBLE DEVS FROM THE PLANNED RTE OF FLT THAT MAY ARISE.
