I'm going to be attending Comic Con Revolution in Ontario, CA, Dec. 18 & 19, and there's going to be some big names there, Chris Claremont (who I'm bringing a stack of books for) Tim Zahn, John Cassaday, etc. CBCS is going to be there exhibiting, but CGC isn't planning to be, but I'm hoping there's going to be someone there who can witness for some CGC slabs, anyone aware of any witnesses/facilitators going?
I know Rocket Comics, who will be there, has done witnessed events at their location, and they said they're still trying to figure out if they'll have witnesses available.
