My fascination with zoos started very early in life when my parents took me to the Canton Zoo. Believe it or not, Canton did have lions, tigers and bears, among other animals housed at Nimisilla Park. Remembering the smell of the monkey house, to this day I still shy away from indoor animal houses. On a recent visit to the Pittsburgh Zoo, I found that elephants have a “green” side. They use dirt as sunscreen and bug repellent.
