Huntsville’s best (and most Huntsville) weekend event right now isn’t a music, arts or food festival. It’s a convention, or in geek speak, a con. Comic & Pop Culture Expo.

This year’s edition, set for April 25-27 at the Von Braun Center’s South Hall, boasts a pretty crazy list of celebrity special guests, including: Priscilla Presley; “Star Trek” icons William Shatner, Walter Koenig and Denise Crosby; “Beverly Hills 90210″ legends Tori Spelling and Brian Austin Green; “Saved by the Bell” icons Elizabeth Berkley and Mario Lopez.
