Today I got a nice postcard from the USA! The postcard features a picture of the Meerkats located in the San Diego Zoo's Safari Park. The San Diego Zoo was first opened in 1916 and currently houses 3,700 animals spanning many different species. The zoo, which covers an area of 100 acres, was the pioneer in open-air cageless exhibits that featured the animals in approximated natural habitats. The zoo is one of the most popular in the world and is run by Zoological Society of San Diego. Thanks Emily!
