Your agent probably belongs to a local association of Realtors and they often have meetings once a month. At these meetings there is often a "marketing session" where some agents stand up and tell about their listings and other agents stand up and tell about their buyers. Your listing agent has an opportunity to "pitch" your house at these marketing sessions.
At the same time, these sessions may not be as effective as they were in the past. One reason is that they are often more social occasions than serious business meetings. Another reason is that, as technology has expanded, local associations have tended to merge and create larger Multiple Listing Services and Associations. Local meetings have become poorly attended gatherings.
