this train got in around 2 or 3am something like 4 hours later than anticipated

I once landed on 91 in Connecticut only to learn that **4 of 5 lanes** were closed for non-existent construction for the length of the state

we only have bad options but the train ranks high!

I've had so many disasters on odd hours Acelas **but** never anything bad enough that would make me interested in driving in NYC or -- God forbid -- Connecticut

1/3 of Boston & Cambridge households are car-freeβ€”among the highest rates for major US cities

Those households are concentrated near T stations, especially downtown, along the Heath St & Boston College branches of the Green Line, and in parts of Cambridge served by the Red Line

I’m not sure what we’re expecting to happen when we don’t provide financial support to what are effectively small businesses w 80% fixed costs which have lost much of their customer base, and don’t have other revenue sources.

AFGE is the largest federal union, representing hundreds of thousands of employees including Alex Pretti

Not entirely sure the comparison is apt

it's fine but I'm spoiled by largely flying JetBlue's Airbus lines, which are ABSOLUTELY nicer

on the way back I get an A319 instead of the E175 which I think makes for a crappy plane hat trick

I'm just really baffled by the Google Photos mention here. Did you forget that you sometimes leave your home? Did the idea that "weather happens" really require a computer vision algorithm?

where do you live that you don't even need 4-season tires, except for when you go into Oklahoma

I think ~everyone should have a personal website, but especially if you're a relatively new grad it's a great idea.

There's been multiple people I've Googled recently where the only web presence I can find is their college sports record - a website lets you control your first impression much more!

Massachusetts state agencies, personally. The MBTA and DOT in particular only post alerts on Twitter!
