Here's a better view of one of the supply modules.
A side view of the ISS Center. Can you see how the fencing is curved? That's because Kennedy Space Center is on a swamp preserve, and there are alligators EVERYWHERE. Alligators can easily jump fences, so they shaped them this way so they fall back and flop over. The employee parking lot, however, has no such protection, so its not uncommon to see alligators in the parking lot and other facilities, and for animal control to remove them.
You think having to use aircraft restrooms is uncomfortable? Try this zero-G toilet on the ISS.
