Wow. When you see it empty like that, it's a LOT smaller than we remember.

The Joe has a date with a wrecking ball just before its 40th birthday this year. Demolition is set to begin soon and is expected to be finished by 2020.

Unfortunately, there won't be a Pontiac Silverdome-style implosion for the public to see. The building is being gutted from the inside out and then gradually disassembled.
They are going to be taking down ceiling beams in the beginning and then proceeding to the exterior by this summer. So you MIGHT be able to see SOME of it, but it won't be a big spectacle.
