Thanks everyone, these are really great!
Only a general schedule for the con has been released so far, but I know he's supposed to be doing at least one Q&A and has signing sessions on all three days (woohoo!). The con is about 600 miles away, so a friend and I are flying down for the whole weekend.
Question- as it's a three-day con, do you think it'll be less crowded on the Friday if we try for autographs then?
