My words have been parsed by an antagonist. There are reasons I believe that Area 78 will not be pursued for a new baseball stadium - numerous failed projects there, the time and costs that would be involved to address major impediments to construction, special infrastructure requirements like a sea wall, storm and sanitary sewer connections, and possible soil bearing where the former river bed was located. The most recent plan approved by the City excluded the old river bed path referring to it as "Crescent park".
As far as GRF, yes it is 35 years old, but there is nothing structurally wrong with it and there are precedents for making major changes to it. Personally, I would not mind seeing a new stadium on the site of the original Comiskey or at another site within Chicago, but not the 78. That's a large hole in the ground that seems like an ideal spot for Amazon or an Intermodal. The owners/developers have been pushing that site for years, but I for one, am not buying in. But anyway, go ahead and buy in if you want to. I don't care.
