Lifelong St. Louis Cardinals fan here. Over my lifetime, they have averaged a pennant about every 7 years and an actual championship every once in a while, so I'm luckier than other fans in this city with their teams. Love catching games at both parks because they balance each other out in pluses and minuses. Basically, Wrigley Field is beautiful to look at, with tons of history and tradition behind it, with very few bad viewing angles. It is also cramped, dingy, with bad plumbing, ridiculous bathroom accommodations and scary chunks of concrete falling everywhere just to keep you on your toes. Sox Park is sterile and functional, with little aesthetic appeal, but plenty of parking/public train access and great food and beer choices. You can also take a piss in a toilet that was designed post-WWII, which is nice. Both parks are very bicycle-friendly, which I appreciate.
So there's my chamber-of-commerce pitch (low and inside!).
More baseball chatter from me later. Great thread idea...
