Critical Mass? LOL
Every day is Critical Mass on the Hawthorn Bridge!
Seriously, I think you'll find that the war is over here and the bicycles have won. You'll need to think about safe and effective bicycling here in the Pacific Northwet. Consider lighting (It's DARK here in the winter), clothing (it rains 300 days a year, and did I mention DARK?), and, of course, you'll want a good lock. Does your bike have full mudguards with a mud flap?
