Taking selfies with hippos at the St. Louis Zoo was all the rage this week. The hippos seemed to be posing for the selfies because they stood perfectly still for the shots, it seemed anyway. The St. Louis Zoo is awesome and free to visit but you need to make a reservation and have a ticket either printed out or on your phone to show them at the gate. And don’t forget to charge up your phone for these once-in-a-lifetime selfies with a real hippo.
