Over the past few months, whenever I've had to drive into Boston, it seemed like a truck would catch fire or rollover on Route 3 and snare traffic for hours. I tried to take the commuter rail from South Weymouth a few times but had to wake up at an obscene hour that was actually closer to my bedtime just to secure a parking spot. But on Sunday, when the Bags sent me home from Jack's child-of-God after party with a boat pass (and some finger sandwiches - yum), I decided to give the commuter boat a whirl. I've taken the boat recreationally for years but never during commuting hours. While it was much more crowded, it was just as smooth. I walked right on and settled in a with my Metro newspaper and a ferry-issue coffee. I immediately felt right at home with the familiar avoidance behaviors of public transportation: Some passengers had their heads buried in laptops and newpapers. Others -- wearing iPods -- displayed the catatonic "I'm not looking at you, I'm looking through you" stare. Since I was bookless and iPod-less on this trip, I pretended to be intensely engrossed in a movie review of "Happy Feet." But then the familiar scene turned bizarre. The boat's horn blasted as we pulled away from the dock and it was like the sounding of the dinner bell. Seemingly out of nowhere, some commuters produced styrofoam containers with full-on lumberjack breakfasts inside of them. Others began stuffing their faces with bagel sandwiches, bowls of cereal, and Zone bars. The guy sitting next to me whipped out a 13"x9" tupperware container and proceeded to eat what appeared to be the remains of someone’s birthday cake. Is this a new commuting trend? I don't ride mass transit as regularly as I used to, but when I did, I never once considered buttering a bagel on the Blue Line or even the 57 Bus. Eating a meal was something you just didn't do on public transportation -- like exfoliating your elbows and heels with a pumice stone. Is this behavior exclusive to the seafaring commuters or is there an intermodal chowdown going on system-wide? I scarfed down a a turkey finger sandwich in my car on the ride to the Shipyard like a civilized human being. But if the rules have changed, I'd like to know. Any insight is appreciated.
