45F with a light wind from the south. Forgot to refill my water bottle but I hydrate before leaving home anyway. Caught the train a mile from the front door, no biggie. However, less than a mile later, some idiot in his 1/2 ton truck cut me off in order to be second at a red light. He just couldn't spare the 1.5 seconds. My anger was translated into pedal power for the rest of my ride in to work, and I again made it in super early.
