This isn't just hometown bias talking: Principal Park is one of the best-looking minor league ballparks around. Home to the Iowa Cubs, this waterfront stadium at the confluence of the Des Moines and Raccoon rivers is a downtown gem. Fans fill the stadium in the spring and summer, always at the top of minor-league attendance rankings. Great promotional giveaways, fireworks, the chance to see former and future big-league stars. Principal Park is a gem.
