School buses are nostalgic for many people. They’re the wild and wonderful social scene that bookmarks the school day. They’re iconic in shape and color, and they have a certain smell that takes former schoolchildren back. But they eventually become too old or outdated to carry kids safely.

What happens to all those retired school buses? They’re the guest room out behind Grandpa’s house. They’re a more colorful element of the street food scene. They’re mobile houses for wanderers who don’t actually want to leave home.

We picked out a few good ones, but there are many more. Let us know in the comments what you’d do with a retired school bus if you had one.
