The town’s Parks and Recreation Department is accepting registrations for the town’s fourth annual Spring Field Day, which is being held by the concession stand at the Ipswich River Park from 1 to 2:30 p.m. May 30. The entry fee is $8, with the event open to children from 2 to 6 years old. The youngsters will have a chance to take part in sack races, a hoop contest, and relay races, as well as soccer and football activities. The event was originally scheduled for May 16 but had to be postponed because the fields were soaked.
