To Chicagoans, great rationale and well put. To mild climate localities, political-like propaganda. Are the 1.5 - 2 months just April/May and late September/October? Because a case could be made, especially by Whale's Vaginaians, that July and August can be miserable as well. Late May through early July, and late August to early September may be the only good weather times in Chicago, especially for baseball. I don't consider anything between mid-May (early June at the latest) and mid-to-late September to be remotely near miserable. Of course, that's just personal preference. November through March in Chicago could cease to exist and I'd never, ever miss it. I'd go as far as including all May through late September as really game on (August is the wettest month, however). April and October are very manageable. This said, November through March is against everything that's good and holy.
