For two decades Friends In Deed has offered emotional and spiritual support for all those affected by life threatening illness, caregiving and grief. In celebration of the 20th anniversary of Friends In Deed, Emmy Award winner Sarah Jessica Parker and Tony Award winner Matthew Broderick hosted 'A Little Jurassic Treasure Hunt,' a once-in-a-lifetime event last night, October 3, 2011. At this special benefit event, guests formed teams to trace clues through the American Museum of Natural History in a specially devised hunt created by legendary composer/lyricist Stephen Sondheim. Following a cocktail reception in The Museum's Hall of Mammals, the hunt took place in the Hall of Saurischian Dinosaurs and the Hall of Ornithischian Dinosaurs before a dinner reception in the Rose Center for Earth and Space.
