Zoey's mother Maggie (Mary Steenburgen) says that she remembers it snowing in San Francisco in 1976 because she had just left a Grateful Dead Concert at Winterland. It did indeed snow in San Francisco on February 5, 1976, but the Grateful Dead did not play any concerts in California until their 2 Day on the Green Concerts in Oakland on October 9 and 10, 1976.
