You ex-LA guys will be singing a different tune come August. Funny story: A woman I work with moved here from St. Louis. That first summer she was angry because "Mickey (Mouse) lied to me!". She thought Florida was always sunny. Nobody told her about the afternoon storms we get during the summer. Also, we don't have a TAP Plastics here. If you are into molding/casting we have a Smooth-On distributor in South Orlando. Look for Reynolds Advanced Materials. One of the finalists from season nine of FaceOff, Scott Fensterer, works there and teaches the occasional class.
Back to MegaCon:
So far for official celebrities we have Stan Lee, Jay & Silent Bob, the original Batman & Robin, and I just got an email saying John Cusack. I think Kevin and Jason are dong some "you have to pay extra to hear us talk" thing. Stan Lee is probably doing his usual pictures and autographs. No idea if the rest will be doing any panels or just charging for pictures and autographs.
Unofficially some of the people from Con Man are going to be there. I think Alan is going, not sure about Nathan.
And I'm sure the green power ranger will be there.
I typically go early Saturday, see a few panels and the costume contest, maybe spend some money, and then blow out of there mid- to late-afternoon to take care of my dog. I would really like to put together a jump suit from "The Expanse", but I'll probably just end up wearing an RPF/Wolverines or Spectrum T-Shirt.
