Well, only if your playing Bike polo it seems or if you are over the age of 17 living in the Northern Territory. This article on ABC online caught my attention. Bike Polo is starting to become a popular sport, having been introduced here from the United States.
I'd say it won't be too long before the powers that be will start to enforce those pesky mandatory helmet laws.
Sadly it is still making the news with the usual for and against on whether the law should stay.
This was in the local weekly mag. , having a go at Canberra cyclists not stopping at red lights and not wearing helmets. Now we wouldn't want riding a bike to appear dangerous now would we. People might actually stop riding a bikes!
