Current mysteries I would most like to solve

— What is that smell? The one on Montague street that has lingered (stronger in the morning, less pungent but still present at night) for over two weeks now, in front of Garden of Eden, the Irish bar, and Hallmark.  A sharp combination of trash, poop, and perhaps something dead, its origin seems to be travelling down the street at a pace of several feet a day.  Other people are wondering this too, as they gag and grimace down the sidewalk.

— What is off-track betting?  Who does this?

— Is pear-ginger jam delicious?
