PLT INADVERTENTLY ENTERED CLASS B AIRSPACE; CTLR INTERVENED; CLRED ACFT THROUGH THE CLASS B.

Narrative

I HAD TAKEN OFF FROM DET AND WAS CLBING OUT ENRTE TO JXN. I CONTACTED DET DEP ON 126.85 TO OBTAIN VFR FLT FOLLOWING. I WAS NAVING BY GND REF; W ALONG 8 MILE ROAD. THIS POPULAR E-W VFR CORRIDOR IS BOUNDED BY THE 3000/8000 FT DETROIT CLASS B MIDDLE TIER TO THE S; THE 4000/8000 FT OUTER TIER ABOVE; AND A GROUP OF 500-1000+ FT HIGH TWRS TO THE N. I REQUESTED A VFR CRUISING ALT OF 4500 FT INTENDING TO STAY BELOW 4000 FT UNTIL CLR TO THE W OF THE CLASS B AIRSPACE. I WAS TOLD TO STAY CLR OF THE CLASS B AIRSPACE; WHICH I ACKNOWLEDGED. I FORGOT ABOUT THE 4000/8000 FT TIER ABOVE ME AND CONTINUED CLBING ABOVE 4000 FT. AT ABOUT 4200 FT THE CTLR INFORMED ME THAT I WAS IN CLASS B AIRSPACE AND WOULD BE FOR ANOTHER 5 MI. I WAS UNAWARE OF THIS INCURSION AND DID NOT UNDERSTAND WHAT HAD GONE WRONG. THE CTLR THEN CLRED ME INTO THE CLASS B AIRSPACE ENDING THE CONFLICT. ONLY LATER DID I UNDERSTAND WHAT I HAD DONE WRONG. THIS INCURSION WAS COMPLETELY DUE TO PLT ERROR. IT WAS COMPLICATED BY THE FACT THAT I WAS RUSHING TO REACH MY DEST BEFORE NIGHTFALL AND THAT I HAD A PAX (MY WIFE) ON BOARD. I TEND TO GET DISTRACTED WHEN SHE IS FLYING WITH ME AND I WANT TO MAKE SURE SHE IS COMFORTABLE. THIS INCURSION COULD HAVE BEEN PREVENTED BY MORE DILIGENCE ON MY PART. IN THE FUTURE; I WILL REVIEW THE AIRSPACE STRUCTURE THAT I AM FLYING NEAR MORE THOROUGHLY. I WILL TRY NOT TO BE DISTRACTED FROM MY RESPONSIBILITIES AS A PLT WHILE FLYING. I WILL ALSO TRY TO AVOID FLYING WHEN I FEEL RUSHED.
