Some art lovers may have had the impression that Eileen Walsh’s Industrial Strength exhibit, which is brilliant, was a one-night affair. Not true! Read the fine print from her press release: “The site will be open for viewing on the following four consecutive Saturdays from 12 until 4pm.” So go back and get a better look every Saturday in March! The place is a little tricky to find, in a row of buildings that doesn’t actually scream out “art!” — so bring your GPS.
