Things to Do in Union City

Led by former NBA point guard and first-year head coach Mark Jackson, the Golden State Warriors charge into the second half of the season. Veteran guard Monta Ellis blows by defenders with an average of 22.2 points per game while forward-center David Lee muscles out under-the-basket rivals for an average of 9.7 rebounds per game. Rookie guard Klay Thompson keeps opponents guessing with the ability to drop shots from all over the court and the inexhaustible supply of riddles he declaims during commercial breaks.

Golfland debuted its first putt-putt green in 1953 and has since expanded to seven locations across California and Arizona. Each location features one to three 18-hole courses, replete with colorful castles, windmills, and fountains. After navigating the obstacle-filled fairways, guests can try their hands at an array of arcade games, whether felling foes in fighting games, stocking up on tickets to win prizes, or following the spellbinding plotline of a pinball game. At the San Jose location, visitors can cool off in the warmer months with a trip down parallel outdoor waterslides.

The next time you're on the roof of a five-story building, look down at the ground, and you'll get a rough idea of just how high people climb at Touchstone Climbing. The gym's seven locations feature lead walls that rise as high as 50 feet off the ground, though height isn't the only dimension that makes the space feel immense. Each spot has at least 11,000 square feet of climbing terrain, not to mention as much as 3,000 square feet of bouldering.

To prevent newcomers from feeling intimidated by the magnitude of the environment, the gym holds introductory classes. During these sessions, participants learn the basic techniques they'll need if they want to conquer the gym's crack systems and boulder problems. The classes are also an opportunity for students to scope out the terrain features at each location, such as Diablo Rock Gym's steep prow, which juts out crookedly like a thumbs up from a dizzy ballerina. While they're at it, the visitors might notice something else: the social nature of the gym. As the San Francisco Chronicle recounts, the fact that lead climbs require two people means that climbers are constantly asking around for new partners and chatting back and forth as they ascend.

Each location also boasts a weight room, cardio machines, and a studio space for everything from yoga to spinning to core classes.

On Sunday, January 3, at 1:15 p.m., the team that once upset the entire steel industry of Pittsburgh and tamed Cincinnati's Panthera Tigris Tigris looks to end the season on a final high note against the Baltimore Ravens (featuring offensive tackle Michael Oher who is the inspiration for the The Blind Side). You'll be sitting in section 354 and have a $10 food voucher in hand.

Although it hasn't quite reached the level of Napa Valley's 400-plus wineries, the East Bay's wine scene has experienced a rebirth—and East Bay Winery Bike Tours intends to ride right alongside as it continues to grow. Led by owner Jon Zalon, the company takes to the streets on two wheels to explore the area's ever-expanding collection of urban wineries and the faces behind the bottles at each stop.

In 2012, Diablo magazine plopped East Bay Winery Bike Tours at No. 10 on its "50 Things You Gotta do This Summer" list. No matter the season, EBWBT's rides present safe, scenic routes that include everything from a trip to an Oakland estuary to a pleasant cruise down Alameda's palm-lined streets—all without having to rent a car or a horse to drive that car. Every tour also makes sure to set aside plenty of time to soak in the surroundings, including picnics packed with homemade food.

Peninsula Symphony, founded in 1949 with the goal of enriching communities with affordable musical productions, grew from a grassroots ensemble to a 90-plus-member orchestra of well-trained local musicians. Music Director Mitchell Sardou Klein leads the ensemble with a steady baton, a sharp ear, and the stamina to carry on through the inevitable triple encore.
