Back in March, the inspirational and aptly-named Mayor Cicero of Castelbuono [Palermo] had the idea of using mules to collect the refuse in this town of 10,000 inhabitants. The scheme seems to be a great success, for, as the Mayor says, this way they are cutting down on pollution whilst saving their historic heritage; the mules also have names and are popular with the town's children.
