DOT DAY: Brown and Warren marching in parade and more

U.S. Senate candidate Elizabeth Warren will be making her first appearance in the annual Dorchester Day Parade on Sunday, where she'll be joined by her chief rival Scott Brown.

Warren will be marching in the third division, while Brown will be in the chief marshal's division. (It's customary for incumbents to march ahead of challengers.)

The two are hardly strangers to Dorchester: Both have featured the neighborhood in their television ads.
