It gets really dark during winter nights here in the Pacific Northwest. Really dark.
"What was that I just ran over?" dark.
It started bothering me when I walked from my car to the gym and I realized that I probably couldn't be seen by the passing cars that seemed so intent at getting a parking space.
It also bothered me when I was in downtown Portland, realized my jacket was black and realized I might as well paint a target on myself (minus the attention getting red paint).
But it really bothered me when I was driving in my neighborhood and only saw a teenager on his bike because his black sweatshirt slipped up a bit from his black pants and I saw a flash of white skin.
So I bought a nice new jacket to wear on walks at night and to/from the gym.
It even has a pocket for my MP3 player.
and I bought two ankle reflective bands to keep in my regular jacket pocket to pull out and apply when the sun goes down and I would like more protection.
If you can't beat 'em...blind 'em!
