This postcard shows a Calder sculpture in a place called the Storm King Art Center in Mountainville, New York, just an hour north of New York City. What an incredible place! 500 acres of rolling hills and woodlands, "celebrating the relationship between sculpture and nature". My friend was there when the trees were red and yellow and orange. Must have been incredible.
More important is her message. Sounds like she'll finally be back to San Francisco (or at least back when I get to see her) for the first time in over 20 years. Hurray!
