Artist Alison Knowles will once again re-stage her 1962 Fluxus performance on Earth Day, April 22nd, hurling large quantities of greens and salad somewhere on or off the High Line. The salad shall be ceremoniously chopped, tossed, served and consumed from 10:00 a.m. to 1:00 p.m., so here’s your chance to eat some art and glean in an artistic, totally not starving artist desperate kind of way.
