I went through all my old slides today and found some gems. Lacking a scanner, I decided to see h0w it would look if I took a photo of a slide projected upon a plain sheet of paper. As I expected, not the best.
Anyway, here are two photos from my experiment. One is of a Halter (or Hartley) boat (I think) preparing the enter the old locks at Gallipolis in 1985. The other is an M/G boat downbound after leaving the locks around that same time.
Now the hard part is finding the ones most suitable for publication and preparing said publication.
