It's hard to believe that the Polina Edmunds story can get any better, but it does. The Archbishop Mitty High School student, who is competing at the Winter Olympics in Sochi, Russia, has committed to attend this year's 25th anniversary of the American Cancer Society's Courageous Kids Day in May.

If you're not familiar with the event, it's one that really tugs at your heart. California's Great America opens its gates each Mother's Day for youngsters undergoing treatment to have a fun day with their families. It's free for the families, including a picnic lunch.

Polina will be a hero for these kids no matter how her figure skating in Sochi turns out. Not only does she expect to be there in person May 11, she's also designated Courageous Kids Day as the beneficiary from the sale of her merchandise being sold at the pro shop of the Sharks Ice skating facility, including "Team Polina" shirts and "Go Polina" mittens.

And you'll have the perfect opportunity to pick something up Friday, when Sharks Ice hosts an Opening Ceremonies viewing party at 7 p.m. The facility is at 1500 S. 10th St. in San Jose.

SIPS AND SUDS: The Teachers Aid Coalition in Morgan Hill is holding its fourth annual Chocolate and Wine for a Valentine on Saturday at the Morgan Hill Community and Cultural Center. The event runs from 1 to 4 p.m. and features apps, chocolate and artwork made by South County artists and students.

Tickets are $25 and available at BookSmart of Morgan Hill and the offices of dentists Don Nguyen and Jon Hatakeyama.

Meanwhile, the Beerwalk returns Saturday to San Jose's historic Japantown neighborhood. If you haven't been on one of these before, it's a great way to sample about two dozen craft beers while also checking out boutiques and other businesses in one of the city's most interesting districts.

The event runs from 2 to 6 p.m. Tickets are available in advance for $30 at www.thebeerwalk.com.

MADE FOR SILICON VALLEY: Members of Congress often use art contests to help spur creativity among students in their districts, but this year the House has launched a new contest to encourage STEM (Science, Technology, Engineering and Mathematics) education by designing apps. No surprise that U.S. Rep. Zoe Lofgren, who carries Silicon Valley's banner, has her San Jose district taking part.

The contest is open through the end of April, and you can get more information, guidelines and tips at www.lofgren.house.gov and at www.StudentAppChallenge.house.gov.
