Heading to the zoo was a very fun experience when you were in your 20s, and in the middle of college. Of course, when you had to live in a dormitory room with 1 roommate, stuff can get distracting quick. Your roommate didn't even like the zoo, even if the animals were radioactive, so you went by yourself.
Of course as you took a look at the zoo, you saw that everything there was packed, as you found a ton of areas located on the map sign that was in the middle of it. You of course decided to buy a flat paper version of the map, before you could actually see anything at the zoo, because you didn't want to get lost in the middle of a huge place filled with animals. There were two different radiation sides to the zoo, whether they turn you into mutants, or myths, that would show their radiation.
