I will be speaking Thursday evening (7 PM), April 30th, at the Iowa State Historical Society building in Des Moines in conjunction with the "official" opening of the 20/20 exhibit. There will be wine and refreshments, a powerpoint and premier of the documentary, "An Arctic Journey in a Changing World," followed by a brief Q & A. I will sell and sign a few books also if you are so interested. Should be a fun evening.
