74F I think when I tried to leave home the first time. I had aired up my tires and lubed my chain on my Surly last night before I went to bed, got up this morning and the front tire was flat. My second in the last two years. Anyway, I switched my panniers over to my newest and hit the road. I did not ride yesterday so my legs were much more rested than usual for a Friday. My newest is my fast bike. And I had a great tail wing. I only regret I had to stop at the school I teach at today, which is withing a tenth of a mile midway on my normal daily commute. Normally it take about 33 minutes to pass the school from my house, today it was about 24 minutes. It woudl have been an all time record commute if I had went the whole way. Tailwinds are beautiful, but they do make you weak, I feel weaker already.
