The two Polar Bear exhibits at this zoo are not the largest by modern standards, but they look great when covered in snow! It seems appropriate for these Arctic mammals.
@snowleopard Honestly, I do think that is a good approach to polar bear exhibits - if a zoo must have polar bears and is on a limited footprint, what they might lack in space they can absolutely make up for in complexity (e.g. Lincoln Park, Saint Louis, Copenhagen, Henry Vilas, *Como in this case*).
