Are ticket prices a deterrent to going to the theatre? October 20 has been declared National Free Night of Theatre day and the Bay Area is one of three cities testing out the idea. “The idea is to attract new audiences and to reward the curious and faithful as well. Participants cover the spectrum from the highest-profile companies to a host of midsize and small groups. Theatre Bay Area, affectionately known as TBA (for obvious reasons), has announced the availability of more than 4,000 free seats that evening at more than 70 large and small companies.”
