I am not sure what exactly this is
but a site for Environmental Science Degrees has posted a list
55 Bicycle Sites to Go Green and Get Fit
it is a great list
it is a great collection of links
it is cool to have Gwadzilla make the list
give it a visit and see if it points you in the direction of a bicycle blog that you can not believe you never heard of before
I wonder if the person who posted this lost the weight they were trying to lose?
