Coming Full Circle

One of the first presentations I made about outhouses was to the Rotary Club in Frankfort, Indiana about 40 years ago. I used a Kodak Carousel Slide projector and 2 x 2 Kodachrome slides. So I guess it was appropriate to again appear before a Rotary Club to speak about outhouses. But this time it was in Cary, NC (yesterday) and the technology was a PowerPoint presentation driven by a Lenovo laptop computer that was displayed on a huge flat screen television using an HDMI cable. The audience responded to questions I posed using handheld electronic responders. The technology had changed but the principles espoused by the Rotarians and the subject matter was still the same.
