SPX! It is at a time that it almost now (ie, tomorrow). And do you know who will be there?
Alexis Frederick-Frost! And he will have copies of Adventures in Cartooning Activity Book.
And Aaron Renier! And he will be on a panel about kids comics on Saturday at 5:00 and also have copies of The Unsinkable Walker Bean!
And also many other excellent people like: Kate Beaton, Scott Campbell, Jon Chad, Robyn Chapman, Shawn Cheng, Becky Cloonan, Ray Fawkes, Jess Fink, Dustin Harbin, Stuart and Kathryn Immonen, Jeph Jaques, Cathy Leamy, Pat Lewis, Alec Longstreth, Dylan Meconis, Corinne Mucha, Dan Nadel, Yuko Ota, Anatth Panagariya, Nate Powell (who may or may not have a mini-comic of his upcoming :01 book), MK Reed (who may or may not have postcards for her upcoming :01 book), Dave Roman, Jim Rugg, Raina Telgemeier, Drew Weing, Maris Wicks, Matt Weigle, and Chris Yates!
Double-plus also: there is a chocolate fountain.
If that is not enough to tempt you (chocolate + comics = awesomeness, I swear!), I don't know what is.
