I was bringing a couple geckos to the vet once, and was driving our old pickup for another quick errand on the way. Before I got to the vet, the fuel tank completely fell off the truck (it wasn't that much of a beater, but the tank straps were rusted it turns out). I couldn't even wait in the truck while someone came to pick me up (fuel fire risk). It was cold, and I had to sit in the ditch for about an hour, but I had the geckos in a styrofoam box with heat packs and they were fine.
