In accordance with a74gent, location not perfect, but Gordon's in Watertown, Ma, had a handful of bottles on the shelf a week ago Friday. I was surprised to see it and promptly grabbed a bottle.
I'm almost positive I saw it on the shelf at One Stop in Haverhill late last week - it's right off 495 and may be worth the call. I've had the best luck calling mid-afternoon, otherwise the help tends to be busy with sandwich orders but the beer guy is still on duty.
