Elmwood Park Zoo, home of zip lines for kids in Chester County, PA, and other local areas, looks forward to hosting the Animals A to Z spring break camp later this month. From March 26th until March 30th, 9 a.m.- 4 p.m., children within the ages of 6-10 will scour the zoo in search of animals whose names correspond to a letter in the alphabet (A is for alligator, B is for bison, and so on).
