The Whitney Museum of American Art isn't real big compared to, say, New York's gargantuan Metropolitan Museum, but it's big enough that there's always something interesting. The current main show is a retrospective of Grant Wood's work. His iconic painting is American Gothic, below, which made him an instant star. You can look at this link to the museum's website while it's still up. Wood, who spent most of his life in Cedar Rapids, Iowa, had a distinct style and a definite dark side.
The other main show was about the photographer and sculptor Zoe Leonard. Frankly, it didn't do a lot for me except for the witty sculpture (for want of a better word) seen farther down - a long line with stacks of old Kodak manuals for the general public.
And if nothing else appeals to you, you can stare at the wall - or read a placard describing a work - or walk your kids around while looking at your phone.
