Lyon was built in 1948, ten years before I was born. Both of my sons went there and I taught them how to ride a bike in its parking lot. When they were really young I used to push them on the swings in the playground after dinner. I've also walked all of our dogs around it literally hundreds of times.
The first, above, shows a group of walruses and a group of penguins set in one of the outside walls. The theme is repeated several times around the school.
