Once and Future Slideshow presentations
Before the explosion in video creation that YouTube has made possible, I sometimes gave informal slideshow presentations at libraries and Rotary clubs. My topics were the moraines and rivers in southeast Michigan, the many beach ridges that cross Woodward Avenue (and that road's history as the Saginaw Trail, the auto era, and the Art Deco masterpieces up and down Woodward Avenue).
I can still do this, on request when my schedule allows. And, I may eventually publish these presentations as YouTube videos.
