People outside conventions with signs.
All I can remember were dates but as under cult mentality I didn't bother to check anything out as I assumed that the dates were not teachings but that some thought these dates represented something. As blondie and someone else pointed out, if you're going to waste your time standing outside a convention have something the JWs can refer to in their own publications or something specific that will make them think without ignoring "useless" dates. Either way most JWs when under mind control will not break free until a circumstancein their life comes along. A way to freedom of mind control is similar to when the cult gets hold of your mind - a weak point in ones life.
