Must have been between October and May. There's no way I would build a new stadium in Texas without a roof. Summertime is simply a beating.Yeah, I know what kind of weather is there in Dallas (I spent 2 nice months in Arlington a couple of years ago...) and that there is no need to build roofs at stadiums in Texas (at least for protecting people from rain). I must admit I know nothing about the climate in Baltimore. Maybe some locals could tell us whether they would like to see a roof at M&T Bank Stadium?
