A few years ago I was interviewed for the WDSE WRPT Public Television documentary “Lost Duluth II”. Its been uploaded to YouTube, and I felt it worthwhile to include it.
The entire documentary is excellent (as is the original Lost Duluth), and the Riverside section starts at 45:20 and ends at 50:29.

You bet! The project is on-going and I’m working with a publisher right now, so the work hasn’t ended at all. I’ll keep you updated.
