What wears a fur coat, but is always naked?

My buddy Paul bikes all winter long, most of us wait until the weather is pleasant to bike in. i am one of them. I used to bike in the winter, and then I got a drivers license and now I'm not so hard core, not like Paul. Anyway, I'm going to be biking again soon, and so will tons of my friends and people around town - either to get to work or leisure or whatnot but all the same, let's watch out for peeps on bikes. The weather has been getting awesome recently. I found this awareness add thing online for the people of London, but it's funny and cool. Check it!
