Bosses, cut your commuting employees a little bit of slack: most people coming into D.C. from the suburbs had a real rough go of it this morning. From the looks of things, some decided to eschew Metro — and its new higher fares — in favor of their car this morning. (They chose…poorly.) Every major interstate around Washington was stuffed to the gills with vehicles this morning, due to several major accidents and high density. MARC — who has been taking a beating after hundreds of riders were stuck for hours on a train without air conditioning last week — ran into a bevy of issues this morning, delaying service on several lines. Traffic once you get into D.C. is no picnic, either. For what it’s worth, Metrorail’s reporting no problems this morning.
