I am looking forward to the (pre) opening of the Sol LeWitt retrospective on November 15.
Sol LeWitt: A Wall Drawing Retrospective, is a collaboration of Mass MoCA, the Yale University Art Gallery and Williams College Museum of Art. It is going to be huge. The aforementioned websites have tons of information on the exhibit. In fact there is a video timeline of the process of an installation at Andover on the Mass MoCA website that is very cool (see images below). The installation will remain on view for twenty-five years, occupying a 27,000-square-foot historic mill building in the heart of MASS MoCA’s campus. so there's no hurry to get there.
If you want to stay nearby, I would suggest the Porches Inn across the street. It's a hoot.
