Randy T. had put this in a comment, but I think it's important enough to move it up into a post:
Pretty disappointed to see so few creator signings locally to coincide with this event (http://www.freecomicbookday.com/creator_signing.asp).
I did, however, notice that Matt Dembicki and Andrew Cohen will be signing at Beyond Comics in Gaithersburg, MD. I only found that since he was signing last year at Big Planet's Vienna, VA store and I figured he'd do so again this year, even though it's not on the creator signings listing at FCBD's web pages.
If you feel like traveling, though, try the following:
Cards, Comics & Collectibles in Reisterstown, MD is having Jimmy Gownley (Amelia Rules!), Steve Conley (Star Trek), and John Gallagher (Buzzboy).
Collector's Corner in Parkville, MD is having Michael S. Bracco (Novo), Tony Calandra (No-One!), Pat Carlucci (Marvel Masterpieces), Ver Curtis (Moonstone Comics), Kata Dales (Lost in the Woods), J.D. Dracoules (Trailer Park of Terror), G.W. Fisher (Shadowhawk), Nathan Getz (No-One!), Ross Kerr (Lost in the Woods), Sunny Lee (Gen 13) [tentative], Chris March (Trailer Park of Terror), H.C. Noel (Mr. Scootles), and Frank Zeigler (Waki & Rusty).
Super Villains Inc. in Nottingham, MD is having Greg LaRocque (Legion of Super-Heroes), Arvid Nelson (Rex Mundi), and Jeff Parker (Marvel Adventures: Iron Man – FCBD 2008 Ed.)
And Washington Street Books in Havre de Grace, MD is having Chelsea Carr (Baltimore Betty), Greg Cox (Star Trek), and Gale Heimbach (Green Hornet).
