Students at Memorial Park School in Waterville recently helped place river rocks along the train tracks in the MPS Victory Garden. The community is invited to a Perennial Picnic in the garden Wednesday, June 13, 6 to 7:30 p.m. Bring a picnic basket and blanket; music will be provided by Midweek Fridays. The garden still needs perennials or $1 donation for fall plantings.
