I spent the weekend at Archon in Collinsville, Illinois. This is the St Louis regional SF con. We had over 1900 in attendance. Tom Kidd was the artist guest of honor and he does some absolutely stunning artwork. In terms of Alternative History he does covers for most of the 143X series of novels in which Eric Flint has sent part of West Virginia back to the 30 years war. he also did the very steampunk-like cover for Fitzpatric’s War. He has a blog with many excellent links here http://kiddography.blogspot.com/.
Since I am staff for the convention I didn’t get to do any gaming myself but it seemed like a good time was being had there. I did notice a huge upswing in Steampunk costumes.
