Ever dream of building the biggest Lego creation ever? At the Lego KidsFest, you can build with bricks to your heart’s content. Activities include a museum of miniature and life-sized models built entirely of the plastic bricks, a Master Builder Academy, where kids can learn building and design skills, the Challenge Zone, where families can compete in speed tower builds, and regular building areas. The Lego KidsFest takes place at the Greater Richmond Convention Center from Feb. 15-17. $18-$20. legokidsfest.com.
