The Parks and Recreation Department is seeking volunteers to help make the summer concert and barbecue series at Ipswich River Park a success. High school students can help out and complete their community service hours. Volunteers are needed for setup, food delivery, and cleanup from 4:30 to 8 p.m. Wednesdays from July 11 through Aug. 15 (and potentially Aug. 22 and 29, if earlier dates are rained out). Advance registration is required for all volunteers. To register, visit the parks department’s page at www.northreadingma.gov and click on the link to Concert/BBQ Volunteer Sign Up. Proceeds from the six-week series benefit Ipswich River Park. For more information, call 978-357-5216.
