This was leg 2 of a 4 leg flight from our home base to destination for the fly-in. I had departed vpz and had flown west to a point south of dupage airport where I turned north. I had contacted dpa tower and received clearance through the class D airspace. There was a lot of wind that day out of the west and I was now having to deal with crabbing into the wind whereas I had had only a headwind so far that day. Anyway I let the wind blow me east of course. I recognized that I was approaching the next layer (1900 ft ceiling), descended to below 1900 ft even though I don't think I was in that airspace. After reaching 1800 ft I rechked the map and noted two antennae near wheaten, il, and realized I may (probably) was not in the B airspace. I had let the wind get the better of me and I suspect dpa tower was watching me on their BRITE scope. I wonder how closely they were watching as my course wasn't what I'd reported it would be and I got too close for my comfort to chicago's class B airspace.

Title: PLT OF A FUNK (SMA, SEL, HIGH WING, TAILWHEEL TYPE), INADVERTENTLY PENETRATED CLASS B AIRSPACE DUE TO A STRONGER XWIND COMPONENT FOR WHICH THE RPTR CORRECTED. HE IMMEDIATELY DEPARTED THE AIRSPACE BY MAKING A DSCNT AND TURN AFTER RECOGNIZING CHART DEPICTED TWRS.
Narrative: THIS WAS LEG 2 OF A 4 LEG FLT FROM OUR HOME BASE TO DESTINATION FOR THE FLY-IN. I HAD DEPARTED VPZ AND HAD FLOWN W TO A POINT S OF DUPAGE ARPT WHERE I TURNED N. I HAD CONTACTED DPA TWR AND RECEIVED CLRNC THROUGH THE CLASS D AIRSPACE. THERE WAS A LOT OF WIND THAT DAY OUT OF THE W AND I WAS NOW HAVING TO DEAL WITH CRABBING INTO THE WIND WHEREAS I HAD HAD ONLY A HEADWIND SO FAR THAT DAY. ANYWAY I LET THE WIND BLOW ME E OF COURSE. I RECOGNIZED THAT I WAS APCHING THE NEXT LAYER (1900 FT CEILING), DSNDED TO BELOW 1900 FT EVEN THOUGH I DON'T THINK I WAS IN THAT AIRSPACE. AFTER REACHING 1800 FT I RECHKED THE MAP AND NOTED TWO ANTENNAE NEAR WHEATEN, IL, AND REALIZED I MAY (PROBABLY) WAS NOT IN THE B AIRSPACE. I HAD LET THE WIND GET THE BETTER OF ME AND I SUSPECT DPA TWR WAS WATCHING ME ON THEIR BRITE SCOPE. I WONDER HOW CLOSELY THEY WERE WATCHING AS MY COURSE WASN'T WHAT I'D RPTED IT WOULD BE AND I GOT TOO CLOSE FOR MY COMFORT TO CHICAGO'S CLASS B AIRSPACE.
