Brave the cold for some outdoor fun during Brooklyn Botanic Garden's wintry events for all ages on the first Sunday of December, January, February and March. When cabin fever hits the family, explore the garden's landscape on a nature walk with naturalist Bradley Klein, as he points out birds, mammals, and insects that remain active during the season. Then little ones can enjoy special hands-on discovery workshops and storytime. Mom and Dad: If you're flying solo, explore cool yoga classes. Check out the venue's website for full details of each month's offerings. All ages.
