Deers were introduced to Sydney’s Royal National Park in 1906. The current population is estimated to be about 1700, and they are considered to be feral pests that are wreaking environmental havoc on a par with cane toads. These road signs appear along the stretch of highway near the entrance to the park, but something has gone awry. Every December (until this year, that is) the signs have sprouted red noses and sleighs for the duration of the silly season, temporarily transforming deer into reindeer, and bringing a dose of humour and good cheer to passing motorists. Altered sign or not, at least the clearway is operational so there’s a good chance that Dancer and Prancer et al (aided by Rudolph) will be able to make their deliveries on time.
