Narrative

THE PLT DEPARTED ON AN IFR FLT PLAN FROM CA TO CANADA. THE PLT OBTAINED A WX BRIEFING FROM OAK FLT SERVICE AND FILED IFR; BUT DOES NOT RECALL BEING GIVEN ANY NOTAMS FOR OREGON. UPON DEP; THE PLT RADIOED OAK ON 127.80 TO INITIATE THE IFR PLAN. CTR RESPONDED BUT DID NOT ACTIVATE THE IFR PLAN BUT RATHER PROVIDED FLT FOLLOWING. UPON REACHING NORTHERN CA; OAK CTR CALLED 'TOO LOW FOR FLT FOLLOWING -- SQUAWK VFR.' THE PLT ASKED FOR A FREQUENCY TO CONTACT ZZZ RADIO FOR FURTHER FLT FOLLOWING BUT DID NOT REACH ZZZ (DUE TO THE LOW ALTITUDE OF FLT). THE PLT OBLIGED TO OAK BY DROPPING THE FLT FOLLOWING AND CONTINUED FLT INTO OREGON AND APPARENTLY; UNAWARE; INADVERTENTLY BROKE THE RESTR AIRSPACE. THE PLT WAS MADE AWARE OF RESTR UPON RADIOING ZZZ CTR FURTHER INTO WASHINGTON. SINCE THE ORIGINAL FLT PLAN WAS IFR; OAK FSS DID NOT MENTION THE NOTAM DURING THE IFR FILING OVER THE PHONE. THE PLT SUBSEQUENTLY CALLED OAK FSS AND ASKED ABOUT THE RESTR. WHILE OR AND WA ARE ACUTELY AWARE OF THIS ADDED RESTR OTHER FACILITIES SUCH AS OAK ARE NOT. THE PLT WAS TOLD THAT THERE ARE 'PAGES' OF RESTRS AND THAT THE 'FLT BRIEFERS DO NOT GET THEM ALL.'
