Animals, wait outside

.

Midreshet Sde Boker or Midreshet Ben-Gurion is a wonderful place down south in the Negev desert.
There is a high school, desert research institutes, a campus of Ben-Gurion University, and lots more.
I get the impression it is a pretty laid-back place.
People come there to live or teach or study or do research because they care about nature and ecology, animals and people.

And that's why I smiled when I saw this sign on a campus classroom building --  I guess people there  have to be reminded not to come in with their pets.
Actually, the Hebrew version says "No entry to animals."
