Narrative:

I obtained a standard WX briefing from milleville FSS prior to my departure from vay. I particularly asked the briefer about tfr's and ADIZ's along my route of flight. I was informed by the briefer of the baltimore class B ADIZ, which extends to the outer ring of the class B, and is from surface to FL180. Also, there was an expanded 10 mi restr zone around P40. I wrote all this down, but did not file a flight plan because I didn't know if I would be able to depart my job to make this flight. My original identify used during the call to FSS was in one aircraft, however, I ended up flying to fdk in another aircraft. I flew direct rtes to each waypoint, which would have kept me clear of the baltimore class B, and thus the ADIZ. Upon landing at fdk, I was informed by a customs enforcement officer that I had violated the baltimore ADIZ. He informed me that the baltimore ADIZ extends beyond the baltimore class B airspace, and beyond the mode C veil. I was not informed by the briefer that the ADIZ extended beyond the mode C veil. The potomac approach operations manager informed me via telephone, that I had violated the baltimore ADIZ, and that I might or might not be hearing from the FSDO. I cooperated fully with the customs officers and the potomac approach operations manager. I apologized to both for any inconvenience, but explained how I wasn't informed by FSS of the extended ADIZ around the baltimore class B.
