I belong to a local naturalists group that has speakers for 6 or 7 months of the year.
We are not a rich group so have to be careful in selecting speakers. We have a policy where we cover the speaker's expenses. Of course that limits getting some of the more prominent speakers. We sometimes have speakers from the local college, grad students from various universities and some scientists doing research. Speakers are quite often looking for publicity about their studies.
Last night we had a speaker on bison. He is connected with the Grasslands park in southern Saskatchewan where they are trying to establish a large herd of prairie bison.
I have always been interested in bison. The speaker we had last night was disappointing in a number of ways. I was expecting to hear about the history and operation of Grasslands Park. There was nothing except in questions after the presentation. I was expecting to hear abut prairie bison in North America. There was very little.
The speaker gave the world history of bison over millions of years and how they got to North America. I was not interested in the long history of bison. So , although the guy was well prepared and knowledgeable I was not interested in the part of the topic he presented.
So close to 100% of our speakers are great and their topics interesting. So one disappointing speaker once in a while isn't bad.
