The above link talks about some design speculation that was taken from a nearly 400 page Environmental Impact Statement regarding our beloved Vikings new stadium. It talks about a material called ETFE which can and has apparently been used on stadiums like the Water Cube in the Beijing Olympics among other planned proposals.
It also mentions something about a roof but seems to discus it in an optional way. I know everything is all hearsay at this point and we'll know in a few short weeks, but speculation is fun in the meantime. Anyone else see something I didn't (or did I see something that's not there)?
