After a too-long absence, i'm back to bicycling to work as my main form of transport. amusingly, i just tripped over this old pictureon a friend's (excellent) site.
I forgot that it is not only great exercise and good for the enviroment, but that it restores a great deal of sanity to my day. As I bike in, I prepare my thoughts and plans, as I ride home I get rid of stress and worry. it's so damn good for you.
