Pocono Snake&Animal Farm - Water Moccasin

Is the mesh the only barrier?

No, there's also glass. The mesh is behind it. Not sure what the purpose is.

This is really awful for photography! Can you add it to the page on worst exhibit design?

@RatioTile Don't I know it! Couldn't use my real camera, couldn't get my phone to focus on anything if I tried to take photos closer than this. I'll try to remember to do that once I'm done with uploads (have this place to finish, plus two more places I went to that day).
