Issued a warning ticket for riding my bike at Ft. McHenry

[From our mail bag:]

All paths within FT. McHenry are closed to cyclist until the new construction is complete Oct 2010. The rangers/federal police officers, informed me there are signs posted. I did not see the sign when I entered the property. The only reason I was given a warning ticket instead of verbal warning is because the director wants to document all encounters with cyclist. Of course they did run my drivers license in their, I assume federal, computer system. Both officers were very polite and friendly, probably because I was open and honest answering their questions. They also liked the One Less Car sticker on my bike. If I would have been issued a ticket, instead of a warning, the fine is $150.
