In Atlanta, Labor Day means Dragon*Con.

The annual four-day event is one of the largest science fiction/fantasy conventions in the world.

Organizers say over 30,000 people attended the event this year which included a panel discussion between the "Star Trek" duo William Shatner and Leonard Nimoy on Friday.

Saturday featured a parade in Atlanta and Sunday evening's Dragon*Con events included an attempt to break the world record for the most people dancing to Michael Jackson's "Thriller."

The Atlanta Radio Theatre Company performed from its science fiction series on Saturday and Sunday evenings.

Dragon*Con wraps up Monday afternoon at the Georgia World Congress Center.
