Funny, this morning riding into school (running late) I had a NASTY headwind. Its ~12.5 miles in a straight line up one street, so no break from the wind. I did plenty of drafting on semis. I usually go for buses too but only the Western Ave. Express - the other one makes too many stops! I was getting pulled at about 28 for a while, which was nice, especially since I could barely turn the pedals at 15mph in the wind.
I also did some skitchin' on pickups, but kept getting freaked out as the pickup trucks neared 35mph... I kept picturing flipping down in front of their rear wheel. Still, I'm getting more confident. Oh, what fun.
