Catching a sporting event when you travel is a great way to experience the local community and be inside an amazing piece of architecture. Even if you don't care for baseball, it's well worth the price of admission (usually not much more than $25 to nearly any stadium for most games). I've always tried to catch games when I travel and have been fortunate to see professional MLB games played in nearly 30 stadiums, some of which are no long standing. Here's the list, as of Spring 2018.
