The Cambridge Street ‘buttoning up’ has commenced: Cambridge Street in Boston this evening resembles a futuristic night battle scene in the first Terminator: giant machines clanking and scraping and rumbling over debris, as idealistic humans dart from one rubble pile to the next etc. ... Except it’s road contractors putting ‘skim coat’ pavement on the street for, apparently, the DNC and, clearly, inconveniencing everyone in sight. Cambridge Street was already a wreck because of a previously inept, slow reconstruction project under way. Now they’re stopping and delaying that inept, slow project for the DNC and putting down a god-knows-how-much-it-will-cost ‘skim coat,' assuming you define ‘skim coat’ as a standard scraping away of an inch or two of old pavement, to be replaced with an inch or two of new pavement, only to be torn up again after the convention. ... Does Mayor Menino really think Mayor Daley et gang are going to be fooled into thinking Cambridge Street is NOT a construction site?  ¶ 8:23 PM
