SMA PLT ENTERS RESTR AREA ON XCOUNTRY FLT.

Narrative

MY WIFE AND I DEPARTED SAN CARLOS; CA (SQL) ON A VFR FLT TO MUSKOKA; CANADA (YQA). THE FIRST LEG WAS TO TERMINATE AT OGDEN; UT; FOR LUNCH AND FUEL. THE WX ACROSS NEVADA WAS SCATTERED CLOUDS AND IN ORDER TO MAINTAIN VFR; I WAS NOT NAVING ON THE AIRWAY. I WAS USING LORAN ALONG WITH VOR. AFTER WELLS; NV; AND PASSING THE LIGHT TERRAIN; THE WX CLRED AND I WAS ON AN INTERCEPT HDG TO THE AIRWAY AS I KNEW THAT RESTR AREAS LAY AHEAD. I THOUGHT THAT I WAS FOLLOWING THE ROAD BED ACROSS THE GREAT SALT LAKE WHICH I KNEW WOULD BE CLR OF THE RESTR AREAS. I MISTOOK THE TRAIN EMBANKMENT FOR THE ROAD BED AND UPON RECOGNIZING THE MISTAKE; I IMMEDIATELY TURNED TOWARD LUCIN VOR (LCV) WHICH WOULD BE N OF R-6040. AS I TURNED; THE LORAN NOTIFIED ME THAT I WAS WITHIN THE RESTR AREA. I FLEW TO LCV THEN DIRECT TO OGDEN. UPON LNDG THE TWR ASKED ME TO CALL HILL AIR FORCE TWR AND I WAS ADVISED THAT I ENCROACHED UPON R-6040. MY MISTAKE WAS NOT TO HAVE CONTACTED SALT LAKE APCH AND ASKED FOR VECTORS AROUND THE RESTR AREA. A CONTRIBUTING FACTOR WAS THAT I HAD SOME CONCERN AS TO THE LOCATION OF THE SALT LAKE TCA. I REGRET THIS MISTAKE AS IT IS THE FIRST IN 20 YRS OF FLYING.
