I realize this is short notice, but my husband just heard about this convention today from a guy at work, and as it's only an hour and a half north of here, we'll be going on Saturday. The 1966 Batmobile will be on display, so will a DeLorean Time Machine and a TARDIS (I feel giddy already!) as well as Christine, the Ghostbusters van, and several vehicles from Jurassic Park.
The fee for a one-day adult pass is $10, a two-day pass being $15. There's several panels on writing and web cartooning that I hope to check out.
I'll write up a review on it later.
