Well my ride home was interesting. After a nice tail wind this AM, I was treated with a STRONG headwind and side wind over the Golden Gate. My coworker who rides the same route as me (but goes even further past me) was leaving about he same time as me and suggested riding together and taking turns drafting in the windy parts. Overall it worked quite well, though I think he took a larger part of the burden as the stronger rider. Definitely makes a difference having someone in front blocking the wind though!
