We spent the afternoon at the New York Botanical Gardens. They had pumpkins on display. (Sadly, we discovered they were all fake pumpkins). D seemed to enjoy posing for the camera, made some music, painted, watched (and laughed) at a puppet show, planted some grass, and played in dirt while looking for worms and such.
