The Peggy Guggenheim Museum is irresistible to me. I've seen the paintings many times, yet they are some of my favorites. The many Max Ernsts (she helped him get his green card by marrying him so he could escape the war), the sexy Leonor Fini, the roomful of Pollocks (she was a great champion of his), the good Picassos, Brancusis et al. Unlike many collections, this one is so personal, and the homelike setting is so congenial to the art.  Like Dominique de Menil she had a strong personal relationship to her artists and it comes through in the idiosyncratic collection.  

Also there is the Albers in Mexico show, which I missed in NY and is small but pithy. The Albers fell in love with Mexico and New Mexico and returned time and again to the Mayan and Inca ruins for inspiration.  Contact sheets of their travels show the intense level of engagement and the reflection in so much of the work. Missing are Annie's weavings. Why?  This was the only thing that rankled.
