Narrative:

I overflew bedford, PA direct hagerstown direct, then mtn direct because the visibility improved after leaving hagerstown. At some point I unintentionally overflew the southeast corner of P40 at 5500'. 31 NM northwest of baltimore I contacted bwi approach and they advised me I had overflown the restr airspace southeast corner and requested my name, full call sign and home base. On landing at mtn, I went to the tower, advised them of the overflt. They called bwi approach, then dca approach, and said the secret service would contact me. I then returned to ilg and went to the tower. They advised me the secret service had already called and tracked me to ilg 3 hours before I got there! I spoke with both a representative of the marine corps, camp david, and the secret service. I could have avoided this whole incident had I double-checked the chart. The other pilot had 30+ yrs of flying, but difficulty with reading close-up and he simply did not notice the small circle P40. He flies in a region with little restr airspace. I had not flown this particular route before and was not familiar with it. It had been a long haul back from tx at 90 KTS, and I simply did not double-check the chart.
