Amesbury Youth Recreation will add 16 new programs this summer for those aged 15 months to 15 years old, and will expand the hours of its preschool program to 9 a.m. to 1:30 p.m. New offerings will include beginner and intermediate skateboard, martial arts, field hockey, flag football, T-ball, the Run 4 Fun cross-country program, gymnastics, and programs titled “Jedi Engineering using Legos,” “Engineering Fundamentals with Legos,” “Amphibious Vehicle and Row Boat Workshop,” “Travel with Harry Potter on a Magical Science Tour,” “Wicked Cool Vet School,” “TV Production with Amesbury Cable Television,” and “Tween Swim Club.” All summer youth programs are self-sustaining, noted Youth Recreation director Kathy Crowley, funded by fees and grants. Last year, Crowley said, the programs served about 1,400 youths in the community. This year the city’s preschool, park, and “tween” programs will also be open to families who do not live in Amesbury. Brochures and registration will be available in March by mail and at the city’s website, www.amesburyma.gov. Registration starts March 8.
