San Francisco Giants

April to October, you can catch one of the 81 home games of SF’s National League baseball team in this intimate ballpark, which changes its name with every telecom merger. The Giants pack in huge crowds and often make the playoffs, but haven’t won the baseball big tomato, the World Series, since 1954 (the team called New York home in those days). Games are frequently sold out, but season-ticket holders often sell unwanted tickets through the team’s Double Play Ticket Window on the website; it’s also worth checking internet auctions like eBay.com and craigslist.org. A behind-the-scenes tour (415-972-2400; tickets $12.50; nongame days at 10:30am & 2:30pm) includes visits to the clubhouse, dugout and field. There’s also a kids’ play structure in a giant Coca-Cola bottle, a mini-replica of the field and the world’s largest baseball glove. Bonus: on the east side of the park, you can stand at the archways along the waterfront promenade and watch a few innings for free.
