get a superflash or die trying.

real lights are a must. pedestrians and trees don't move at 15 mph.

if you can't ride 30-40 miles at a slow pace you need to ride more, that's the end of it. biking is great even if you never go more than five miles, but for me i don't feel like i have gotten outside until i've gone ten, especially at a normal leisure-ride pace.
