They have to play outdoors in the Midwest and Northeast eventually. what is the difference if it is 40 and raining on april 1 or april 11th? The weather in April sucks for half the country. Really, in the NL teams like Pitt, Philly, Wash, NYM, Chicago, and Colorado should have domed stadiums, it just makes too much sense. I think Minnesota is building a stadium with no dome. Oof, what a mistake. They havent watched an outdoor game in Minnesota either football or baseball in what, 40 years? They have no idea what they are in store for. Places like St. Louis, Cincy, and SF should be ok in April, Washington might also be a swing stadium, as I know it gets nice in DC much earlier than in the Midwest.
