Underground at Ink Block

The Underground at Ink Block is the city’s latest triumphant effort to repurpose a forgotten space, this one tucked underneath a knotty snarl of South End/South Boston overpasses. The eight-acre park includes bike paths, boardwalks, a dog park and more than 150,000 square feet of mural work by artists from Boston, Los Angeles, New York and Puerto Rico. There is no better excuse to check it out than the Wednesday night bootcamps. Okay, fine, the pop-up bar is pretty convincing as well.
