To hell with what Pennsylvania groundhog Punxsutawney Phil says about there being six more weeks of winter; if you want a true harbinger of spring, head over the Center for Architecture for a last chance to check out the “Two Wheel Transit” show mounted by the DEP for their bike share program that going to be launched in the spring. The show teases out some of the details of the plan that will add rentable public bikes to the New York City’s transit options. The exhibit closes this Saturday, but if you don’t make it over in time, you can go to one of the community bike share workshops that begin on Monday. The first meeting will be held at 25 Carmine Street. The workshops will give New Yorkers a chance to comment on where to put the 600 bike stations.
