We love this zoo and are probably here 4-6 times per year. We stopped by today (2 November 2013) to meet up with some friends and enjoy the zoo. The wolf and meerkat exhibits are our personal favorites, but we love most of them. We haven't seen a cache dedicated to the zoo, so we happened to have a container that was prepared for a possible missing cache in the Chicago Lakefront Trail series; however, that cache was still there, so we felt we had to use the container. Everything came together and so this cache was born. Please enjoy it and take some time to enjoy the nearby zoo, named after the area in which the cache is located, Lincoln Park.
