Boon Sheridan was amazed at this preemptive space saver in Everett this morning.

Around 10:18 p.m., people from the Rhode island line to North Chelmsford reported their lights flickered. Around the same time, people in Allston reported "a HUGE explosion" and "a massive flash of light in the sky."

BPD and BFD are investigating a report of a possible explosion at an NStar substation off Alcott Street in Allston.

UPDATE, 10:40 p.m.: BFD found no fire or evidence of explosions or giant, freshly opened cocoons at the substation, so departed.

The last time everybody's lights flickered.

The Boston Fire Department reports a driver somehow managed to drive in reverse into the Artful Edge, 55 Harvard Ave., around 4 p.m. Arriving emergency crews found the Subaru embedded in the framing store. The driver was unhurt, but one pedestrian was cut by flying glass.

Police are investigating the incident; ISD also arrived to look at the structural state of the building.

Luke O'Neil says farewell to the Pill, a long-running Friday-night indie dance party that ends tonight.

A frustrated citizen in Allston sighs:

Tags and stickers everywhere in Allston. Where to start? who cares. it's Allston and nobody cares. waste of city resorces to bother, no?

MuckRock posts some FBI files on the former BU president.

Kara Sassone reports a bus with a large Penn State Nittany Lion on the back is the reason so many Storrow Drivers are fuming this rush hour - he managed to get to the BU bridge inbound and then almost got Storrowed there. Or as somebody from the team put it:

So we have been on the road all day..are 400 feet from our last exit and the bus can't get under the last bridge on the interstate.

Alice, who took the photo, reports from the scene:

Pedestrian safety, physically separated cycle tracks, and opposition to a proposed fence were front-and-center last night in Allston at a Massachusetts Department of Transportation meeting about the reconstruction of Cambridge Street between Harvard Avenue and Lincoln Street.

More than 150 people attended the meeting, including Allston residents, business owners and transportation experts. Many wore stickers that read "Union Square to the Charles River:" A common theme was that MassDOT and the city of Boston, which both own parts of the road, need to come together on a plan to improve all of the Cambridge Street.

MassDOT is holding another public meeting about the Cambridge street overpass of the Mass Pike.
