this morning, sunny, extra layers, no wind, 16F. going down hills hurt my forehead from the wind chill. my water bottle had iced up by the end of my 20 minute ride. i'm looking forward to the above 30F temps this afternoon for my ride home. why? no pain, no gain. no biking, no blood pressure lowering, no wallet fattening from no gassing up the car, no contribution to global green house gases, no quiet, no radio, no finding a dollar bill on the road, no sense of accomplishment.
