Narrative:

I fly a C185 float plane daily between our office and a lumber mill from may to nov, 5 days a week. I have been doing this consistently for 31 yrs, averaging over 100 times per yr. I stay clear of all control zones and well below seatac TCA. I just simply did not know that the president was in the seattle area and accidentally flew into a restr area and was notified by a military aircraft, after which I called the FAA and gave them all information they asked for.
