Fresno Grizzlies

Everyone can buy up to five of today's Groupon (a total of 10 tickets), so round up ballpark fanatics of all ages for a Saturday-evening outing to the open-air Chukchansi Park, which plays host to the Fresno Grizzlies before they grow to the heights of gentle yet surprisingly man-sized San Francisco Giants. Backdropped by the downtown skyline, night games spring to life under a spectacular night sky. During slow innings or unusually long pop flies, take your anxious youngsters down for a few games at the park's Fun Zone, where kids can train like real-life baseball players by riding the carousel, rolling down the inflatable slide, and practicing in the pitching and batting zones.
