MEDFORD — It is an ordinary working-class neighborhood: clapboard houses, chain-link fences. There is a statue of the Virgin Mary in one front yard; in another, a Halloween ghost waves in the wind.
But something extraordinary is happening here. Fences are coming down. Aluminum bleachers are going up. Thursday morning, a crew will begin erecting a 280-foot-long tent, large enough to fit more than 1,800 people.
