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.
