I've heard from several of the businesses the same thing. Memorial Day. I also asked some of the area administrators from AMC and they concur but they all seem a little skeptical about it. AMC puts grand openings on it's site usually two months prior to opening so maybe we'll hear something official soon.
If you look behind the plywood barrier there seems like a pretty good amount of work to be done structurally (windows, cabinets, painting, etc.) Which I think think they shouldn't have a problem getting done but I never see anyone working on it? Not to mention all the signage and projectors need to be installed, sound systems, etc. They have their work cut out for them. I sure would like the chance to see Indiana Jones here though.
