Sub-titled "A Fan Run Science Fiction Convention", Shore Leave in Baltimore largely features guests from TV and movies, such as the Star Trek and Star Wars franchises, Stargate, Xena, and this year, Dollhouse, among others. They also feature authors, some of whom happen to work in the comics field, including the following:
Mike W. Barr
Peter A David
Michael Jan Friedman
David Mack (the less-famous one who has worked at Image)
...and perhaps some of the other authors whose names didn't ring a bell right off the bat for me. Check out the bios and homepage links from the Guests section of the show's website.
The show is July 10th-July 12th at the Marriot's Hunt Valley Inn.
