I want to address the salmon issue.
I'm a cyclist and a runner. I follow the established protocols for both activities, riding with traffic while doing the former and running against traffic while doing the latter. I'm a relatively new cyclist, but I'm a 35+ year suburban and NYC runner. I can't tell you how many times as a runner, I've had to freeze in my tracks when a car was making a right turn either didn't look to their right at all, rolled quickly through a stop sign or both. In nearly every instance, had I been cycling, even as slowly as 10mph (16kph), I would have been struck by a car.
Here in the suburbs, my bike club and all the other "spandex" people I know ride with traffic with helmets.
On a daily basis, I see teenagers riding salmon without helmets. I've witnessed 2 or 3 close calls and one instance where the car turned and the cyclist went up and over the hood, somehow lucky enough to land just about on his feet. But every time I see people doing it, I cringe.
