FYI, MARC is a commuter train system that runs three lines through Maryland into DC: Two from Baltimore and beyond to the east, and one from the panhandle of West Virginia.

Preety Gadhoke isn't a famous artist. She's a graduate student in environmental health at Johns Hopkins University in Baltimore. But she sees the world in ways she wants to express, and she's trying to do that through photography.
That's how she ran into the MARC police.
Gadhoke, 32, is taking the "Joy of Photography" course at the Smithsonian Resident Associate Program. One morning this month, after her teacher, Falls Church photographer Olive Rosen, assigned students to document a day in their lives, Gadhoke took her Nikon F10 to the Odenton MARC station near her home in Anne Arundel County. She took pictures of the starkly beautiful curved iron lampposts along the platform.
Ten minutes into her exercise, a police officer approached Gadhoke and asked what she was doing. She explained her assignment. The officer replied that three commuters and a train conductor had reported her for "suspicious activity." No one had said a word to Gadhoke.
The officer asked Gadhoke for identification and her roll of film. She complied. He took her driver's license and the film and had her stand in the parking lot for 40 minutes. While he ran a check on her, Gadhoke's commuter train rolled past, passersby stared at her and the station agent came outside to ask what was going on.http://www.washingtonpost.com/wp-dyn/content/article/2006/02/25/AR2006022501641.html
