No hard facts @eball. Just a sneaking suspicion based on my initial conversation with my Legends rep. When I said ideally I wanted coverage and heat, she said something to the effect of "well some club owners might not renew so there could be some of those left." Uh no. I'm not buying clubs. And I recall the survey describing non-club heated and covered seats at a certain price point that I was definitely interested in.
My memory isn't the best but I could swear when they started talking about this stadium it was supposed to be 85% covered. Now it's 60-something%, right? And @SoCal Deek if prices are ballooning (and overruns are 100% on Terry) they can easily take out things like heat in certain sections. It wouldn't require a redesign. Just don't wire and install them. Maybe the thought is they'll do it later.
