Some sort of Halloween event is being held today at the Botanical Gardens in Roger Williams Park. Everything at the park is well worth a visit: Zoo, Natural History Museum, Planetarium, Botanical Gardens (in a vast greenhouse-like conservatory), and the park itself, designed by the same guy that designed Central Park. On a peak-foliage day like today it will be gorgeous. (And there's a jackolantern event there too, but it's at night.) Apsara, quite near the Elmwood entrance, is great food.
