What does the speaker imply about the audience?

I am delighted to see that we have such a full house for this afternoon’s lecture. I can see by the overwhelming attendance that today’s topic and the new exhibit are of interest to many in our community. The photographs, which are on loan from a number of local businesses and private collectors, trace the history of the area from its beginning as a small stop on a nineteenth-century railway line to its current status as a modern city. And that is what we have asked historian and storyteller Marc Wise to share with us today.
