It was just fine, thanks for asking. 10F, 2F windchill. No problem. After 40 min my toes were cold but nothing a nice warm shower couldn't fix. All I had on was wool socks and well ventilated summer cycling shoes (me = idiot). Happy as a frickin clam. I'm banking on 30's tonight and 40's tomorrow. God I love St Louis. If you don't like the weather, stick around for a few days, it'll change.
