Opening day is getting closer. Driving past the new location of the in Williamstown on Thursday, GreylockNews.COM noticed that a new copy of the familiar Wild Oats sign has been fixed to the top of the former Dox store where Wild Oats will relocate in July. The customer-owned cooperative foodstore is nearly doubling its floor space. On Thursday, there were already shelves in place with non-perishable goods neatly positioned. Two check-out counters are set up and some lighting was in place. Wild Oats Cooperative Inc., the Williamstwn coop, is not connected with the national whole-foods chain, Wild Oats Markets, Inc., and actually took the name "Wild Oats" in retailing years before the national group. On May 17, Williamstown voters at town meeting approved tax-increment financing for the $1-million Wild Oats move.
