In What Year Were the First Kegs of Harpoon Tapped in Boston?

I ask this week’s question because Boston will host the Beer Bloggers Conference starting on Thursday; and because the Mass. Bay Brewing Co. (a.k.a. Harpoon) was the first craft brewery in Boston since Prohibition. Extra points for the exact date; the bars in which they were tapped; and the neighborhoods, too, why not?
