These pictures were taken, mostly at Madison International Folkdancing, during 1977-79 when I was in the UW Math Dept and during the summers 1980-85 when I was teaching in Pennsylvania but spent summers in Madison. I used a Canon AE-1 camera.
You can view the Albums as a slide show below or download a .zip file of all the albums
here. On a Mac, after unzipping, Xee (free software) works nicely as a slide show viewer.
It will take a little while to load each slide show.
