Sunday Signage > Slow Down

I was talking to some fellows who have lived on Gabriola for a long time and apparently, as recently as the 1970s, signs like this were totally unnecessary. Everybody used to drive like little old ladies but unfortunately, not anymore. Nowadays, people drive like maniacs, speeding everywhere and endangering their neighbours and wild and domestic animals in the process. Seems so out of place on this otherwise calm and peaceful little island. What's the hurry?
