Shore Leave

Shore Leave is an annual fan-run convention that takes place in the Baltimore area, MD (USA). It was founded by the Star Trek Association of Towson (STAT), which continues to run it. The first convention took place in 1979. 

The con's focus was initially on Star Trek, but it has since broadened to include other science fiction media. The programming includes guest appearances by actors, writer/creators, and scientists, a dealer's room, an art show, a film and video festival, children's programming, workshops, and a cosplay/masquerade show/contest.
