The PR Society is again threatening to block coverage of its annual conference starting Saturday in San Francisco.

Here is a video interview with Jack O’Dwyer by Dave Armon of Critical Mention outside of the exhibit hall. A guard can be seen in the background trying to hide.

CM this year will host the “Critical Mention Lounge” at Jillian’s, a block and a half from the S.F. Marriott, where the PRS conference will take place. Jillian’s has pool tables and vintage arcade games.

Critical Mention, a sponsor of the PR Student Society conference, will provide food and drinks from 8 a.m to 9 p.m. Sunday and Monday. Jack O’Dwyer will play the piano from 5-7 p.m. on Sunday and PR pro Shonali Burke will have a guitar duel with Brian Pittman of Bulldog Reporter at 7 p.m.
