North Stratfield School is 50 years old, and on Sunday that anniversary will be celebrated at a community party.

The birthday picnic is planned from 4 to 7 p.m. at the school, 190 Putting Green Road. It will take place rain or shine, according to PTA organizers.

About 500 people are expected to attend, with activities including a dunk tank, DJ, raffles, family pictures, and catering by Taco Loco.

The North Stratfield PTA is selling 50th anniversary t-shirts to commemorate the occasion.
