Saturday, May 5 is Conservation Day, and the City of Woburn is turning out to celebrate! Join WREN and The Friends of Spence Farm in their clean-up efforts. WREN members will be at Horn Pond pulling out overgrown plants and planting new shrubs and flowers in the memorial plot at Ice House Park. At Spence Farm, people will be picking rocks from the field, pulling limbs from the pond, staining the picnic tables, hay wagon deck, and seats, among other things. People are encouraged to bring gloves, rakes, shovels, and any other hand tools you may need. Sign-in is at 9am for both the Horn Pond clean-up, on Cove St., and the clean-up at Spence Farm, 41 Wyman Street.
