With temperatures hovering around freezing, gray and overcast skies almost every day, and snow in the forecast, the only way we’re getting through this winter is thinking about lovely summer days to come. And what says summer more than a picnic in the park? Artist Tamara Johnson’s aptly titled Picnic was specifically created for Maria Hernandez Park and the surrounding Bushwick community, and lets us imagine, if only for a moment, that it’s warm enough to eat outdoors. The hand-cast concrete picnic scene “symbolizes the gathering, relaxing and sharing we experience with friends and family” and turns “a temporary happening into a static monument for participation and contemplation.” The sculpture is on display until the first day of spring (March 20).
