Aug 14, 2008 — The Potsdam Walmart parking lot was jam-packed. The 188,000 sq. ft. Supercenter just outside Potsdam on the main road to Canton opened its doors yesterday. The grand opening ended a decade-long quest to locate in the community. There was a site change, public hearings with volatile exchanges between Walmart foes and friends. There was a court challenge that lasted more than a year, and a dust-up between the village and the retail giant over extending a sewer line to the store. David Sommerstein hit the streets of downtown Potsdam for reaction yesterday. He spoke with Martha Foley.
